The exhaust system from the catalytic converter back has less effect on power than the headers, but its contribution to overall exhaust tone, back-pressure reduction, and the aesthetic presentation of the vehicle is significant enough to make it a priority upgrade for any serious build.\u003c\/p\u003e\n\u003cp\u003eWith 494 exhaust system products from Flowmaster, Hooker, Flowmonster, and Hooker Blackheart, our exhaust system range covers complete cat-back and axle-back systems, pipes, X-pipes, and Y-pipes for the most popular American performance vehicle applications.\u003c\/p\u003e\n\u003ch3\u003eCat-Back Exhaust Systems — Complete Solutions\u003c\/h3\u003e\n\u003cp\u003eA cat-back exhaust system replaces everything from the catalytic converter back to the exhaust tips — typically including the connecting pipes, resonator, muffler, and tips in a matched set designed to work together as a system. The advantage of a complete system over individual components is that the pipe diameters, bend radii, and component specifications are engineered together for consistent flow and sound character — producing a result that's more predictable than mixing components from different manufacturers.\u003c\/p\u003e\n\u003ch3\u003eX-Pipes and H-Pipes — Crossover Flow\u003c\/h3\u003e\n\u003cp\u003eOn V8 engines with dual exhaust systems, an X-pipe or H-pipe connecting the two banks balances exhaust pulses between them and reduces back-pressure. The X-pipe design produces a smoother, higher-pitched sound character and marginally better flow; the H-pipe produces a deeper, more traditional V8 exhaust note while still reducing back-pressure compared to no crossover at all. Both designs can produce measurable power improvements on well-tuned exhaust systems, and the choice between them is partly a power consideration and partly a sound preference.\u003c\/p\u003e\n\u003ch3\u003eIndividual Exhaust Pipes for Custom Installations\u003c\/h3\u003e\n\u003cp\u003eIndividual exhaust pipes in mandrel-bent configurations allow the construction of custom exhaust systems around specific routing requirements — essential on engine swap builds and custom vehicles where no off-the-shelf system exists. Mandrel bending maintains consistent internal diameter through bends, preserving the flow characteristics of straight-pipe sections through the curves required by any practical routing.\u003c\/p\u003e\n\u003c\/div\u003e","products":[{"product_id":"d660-0009a","title":"Dinan Free Flow Axle-Back Exhaust - 2006-2010 BMW M5","description":"\u003cdiv class=\"billy_features_content\"\u003e\n  \u003ch3\u003eOverview\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cp\u003eThe Dinan M5 Axle-Back exhaust system provides maximum flow characteristics for optimum power gains while producing a civilized yet very sporty exhaust note that is appropriately aggressive at wide-open throttle.

Winning back-to-back-to-back Rolex Series Daytona Prototype racing championships in 2010, 2011 \u0026amp; 2012 along with the top two podium spots in 2011 and winning in 2013 the grueling 24 Hours of Daytona as the engine supplier to Chip Ganassi Racing. You can rest assured that you are purchasing the most leading-edge technology on the market. Who else do you want to tune your BMW if not the company that beats the competition in power and durability in the most competitive road racing circuit in the U.S? | What else would you expect from Dinan but the most technologically advanced exhaust on the market? The problem with most performance type exhaust systems is they compromise both flow and sound quality to try and achieve a balance between the two. Dinan's Free Flow Axle-Back Exhaust employs leading-edge technology to solve this problem with advanced features not found in most aftermarket high-performance exhaust systems, including a Helmholtz chamber and single-channel absorption increases flow while reducing unwanted noise and weight. | The Helmholtz chamber is a resonance cavity that reduces the drone that most high-performance exhausts have at light throttle cruise. In addition, Dinan has a straight-through single pipe design to further reduce noise at light throttle cruise, so that it is a civilized exhaust that you can live with every day. | The single-channel dual exhaust is a full 10 lbs lighter than the stock BMW part. The Dinan Free Flow Axle-Back Exhaust is a sporty sounding exhaust at wide-open throttle when you want it but also quite and civilized when you are at light throttle cruise. This is consistent with Dinan's core philosophy of \"Performance Without Sacrifice\". One of the reasons you purchased your BMW is because of its level of refinement.

Winning back-to-back-to-back Rolex Series Daytona Prototype racing championships in 2010, 2011 \u0026amp; 2012 along with the top two podium spots in 2011 and winning in 2013 the grueling 24 Hours of Daytona as the engine supplier to Chip Ganassi Racing. You can rest assured that you are purchasing the most leading-edge technology on the market. Who else do you want to tune your BMW if not the company that beats the competition in power and durability in the most competitive road racing circuit in the US? | What else would you expect from Dinan but the most technologically advanced exhaust on the market? The problem with most performance type exhaust systems is they compromise both flow and sound quality to try and achieve a balance between the two. Dinan's Free Flow Axle-Back Exhaust employs leading-edge technology to solve this problem with advanced features not found in most aftermarket high-performance exhaust systems, including a Helmholtz chamber and single-channel absorption increases flow while reducing unwanted noise and weight. | The Helmholtz chamber is a resonance cavity that reduces the drone that most high-performance exhausts have at light throttle cruise. In addition, Dinan has a straight-through single pipe design to further reduce noise at light throttle cruise, so that it is a civilized exhaust that you can live with every day. | The single-channel dual exhaust is a full 10 lbs lighter than the stock BMW part. The Dinan Free Flow Axle-Back Exhaust is a sporty sounding exhaust at wide-open throttle when you want it but also quite and civilized when you are at light throttle cruise. This is consistent with Dinan's core philosophy of \"Performance Without Sacrifice\". One of the reasons you purchased your BMW is because of its level of refinement. You won't ruin the refined characteristics of your BMW when you use Dinan performance products. This level of development takes time and is the reason Dinan is usually not the first company on the market but you will find it is worth the wait. | Durability is also a primary concern at Dinan.

To date, Dinan has been synonymous with welded on, thin-walled tips and a philosophy of exuding a civilized note when you want it to be, and a pleasantly aggressive one under hard acceleration. While the mantra is maintained, albeit tweaked with the emergence of mid-pipes and resonator deletes to those who want an even more aggressive sound, the styling of the tips is being drastically transformed. The new massive 4\" diameter tips on the M550i exhaust are the biggest we have done thus far in addition to being double-walled the polar opposite of our normal thin-walled style. Perhaps most importantly however is the new tips are clamp-on. Not welded as in the past, so they can be easily swapped to new styles or replaced as the need arises. | Internally, the exhaust is typical of other Dinan exhausts and is designed to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow. Like all Dinan exhausts, our M550i Free Flow Axle-Back Exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. In fact, on the G30 M550i equipped with a Dinan exhaust, you will be astounded at how eerily quiet it is in the cabin.

To date, Dinan has been synonymous with welded on, thin-walled tips and a philosophy of exuding a civilized note when you want it to be, and a pleasantly aggressive one under hard acceleration. While the mantra is maintained, albeit tweaked with the emergence of mid-pipes and resonator deletes to those who want an even more aggressive sound, the styling of the tips is being drastically transformed. The new massive 4\" diameter tips on the M550i exhaust are the biggest we have done thus far in addition to being double-walled the polar opposite of our normal thin-walled style. Perhaps most importantly however is the new tips are clamp-on. Not welded as in the past, so they can be easily swapped to new styles or replaced as the need arises. | Internally, the exhaust is typical of other Dinan exhausts and is designed to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration.

In fact, on the G30 M550i equipped with a Dinan exhaust, you will be astounded at how eerily quiet it is in the cabin.

Form and function reign supreme from the factory in true German form. On the other hand, other aspects may not be as carefully cultivated. The stock exhaust note on the F90 M5 as an example, while no slouch, is probably best described as having a subdued aggressive note. Dinan believes for such a powerful and impressive car however that the vehicle deserves to be able to bellow a bit louder and more aggressively. The F90 M5 is the alpha on the public roads after all. Dinan's goal is to let the machine sound the part in addition to performing it. With Dinan, there is no reason to sacrifice anything in the process to meet that goal either. Whether that be in the form of drone, civility, appearance or any other aspect. | In order to achieve desired sound volume and tone, Dinan felt becoming of the F90 M5 the tubing was enlarged to 83mm (vs 80mm stock) to allow freer flow throughout the entirety of the system. The larger tubing is fed into a muffler that is typical of all Dinan exhaust design and utilizes absorption and reactive technologies designed to improve exhaust flow and reduce backpressure. The combination results in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow and greater sound as the bulk of the gases are bypassing the muffler. Like all Dinan exhausts, our M5 free flow exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. With the Dinan exhaust equipped on the M5 you get the best of both worlds; aggressive tone\/sound and civility. A combination that we have termed internally as \"refined aggression.\" | Sound isn't the only aspect of the exhaust that has been modified. The Dinan F90 M5 exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color. The entire system is then brush finished to further guarantee an immaculate looking system out of the box. The attention to detail is not limited to parts of the system you can't see once the exhaust is installed but is also extended to the exhaust tips themselves.

Form and function reign supreme from the factory in true German form. On the other hand, other aspects may not be as carefully cultivated. The stock exhaust note on the F90 M5 as an example, while no slouch, is probably best described as having a subdued aggressive note. Dinan believes for such a powerful and impressive car however that the vehicle deserves to be able to bellow a bit louder and more aggressively. The F90 M5 is the alpha on the public roads after all. Dinan's goal is to let the machine sound the part in addition to performing it. With Dinan, there is no reason to sacrifice anything in the process to meet that goal either. Whether that be in the form of drone, civility, appearance or any other aspect. | In order to achieve desired sound volume and tone, Dinan felt becoming of the F90 M5 the tubing was enlarged to 83mm (vs 80mm stock) to allow freer flow throughout the entirety of the system. The larger tubing is fed into a muffler that is typical of all Dinan exhaust design and utilizes absorption and reactive technologies designed to improve exhaust flow and reduce backpressure. The combination results in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow and greater sound as the bulk of the gases are bypassing the muffler. Like all Dinan exhausts, our M5 free flow exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. With the Dinan exhaust equipped on the M5 you get the best of both worlds; aggressive tone\/sound and civility. A combination that we have termed internally as \"refined aggression.\" | Sound isn't the only aspect of the exhaust that has been modified. The Dinan F90 M5 exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color. The entire system is then brush finished to further guarantee an immaculate looking system out of the box. The attention to detail is not limited to parts of the system you can't see once the exhaust is installed but is also extended to the exhaust tips themselves. The Dinan exhaust sports enormous, quad 4\" (102mm) clamp-on, double-walled, black ceramic coated and laser engraved exhaust tips.

What is viewable are impressively large quad 4\" (102mm) exhaust tips. Available in polished stainless or matte black, the signature Dinan straight cut tips offer a much more agreeable, and aggressive, focal point than the stock setup. | With the outward styling and look enhanced, improvement upon the raspy sound of the S55 motor was necessary. To accomplish this an overhaul of many facets of the stock system needed to happen. The internal baffling of the can has been completely redesigned to allow a more Dinan inspired note to be heard (deeper and throatier). The piping has also enlarged to allow freer flow and bring the tone even deeper yet. While these things all make the system a respectable representation of a Dinan M exhaust, what really sets the system apart is the incorporation of an 'X' in place of the factory resonator. Not only does the overall volume increase, but the crossover allows for a refined and smoothened exhaust note complete with a perfect mix of exotic undertones and raw aggression. Combined, these features transform the raspiness of the S55 into a more agreeable Dinan inspired aural experience that keeps you wanting more.\u003c\/p\u003e\n    \u003cp class=\"mt-2\"\u003eStainless Steel - Black Tips - F87\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003chr\u003e\n  \u003ch3\u003eFeatures\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cul\u003e\n      \u003cli\u003eMore Power: + 6 HP @ 6300 RPM, + 5 LB-FT @ 6300 RPM\u003c\/li\u003e\n      \u003cli\u003eEnjoyably louder, sportier sound\u003c\/li\u003e\n      \u003cli\u003eQuad 4\" (102mm) diameter clamp-on, double-walled, ceramic coated and laser engraved black exhaust tips\u003c\/li\u003e\n      \u003cli\u003eFactory resonator replaced by an x-pipe for increased volume and an improved throaty note\u003c\/li\u003e\n      \u003cli\u003e100% 304 stainless steel construction\u003c\/li\u003e\n      \u003cli\u003eLarger diameter piping for increased flow (70mm vs 65mm)\u003c\/li\u003e\n      \u003cli\u003eComputer controlled exhaust valve functionality is retained and limits noise during low speed driving and opens fully during high-load conditions\u003c\/li\u003e\n      \u003cli\u003eEasy bolt-on installation with included mounting hardware\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n  \u003ch4 class=\"mt-3 mb-1\"\u003eTECHNICAL SPECS\u003c\/h4\u003e\n  \u003cdl class=\"billy-specs\"\u003e\n    \u003cdt\u003eLength\u003c\/dt\u003e\n\u003cdd\u003e46\u003c\/dd\u003e\n  \u003c\/dl\u003e\n\u003c\/div\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":50548054032678,"sku":"D660-0082-BLK","price":2213.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/1666\/1542\/files\/D660-0082-BLK_1.jpg?v=1776353870"},{"product_id":"d660-0086-blk","title":"Dinan Free Flow Axle-Back Exhaust - 2020-2025 BMW X3M\/X4M","description":"\u003cdiv class=\"billy_features_content\"\u003e\n  \u003ch3\u003eOverview\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cp\u003eThe \"baby M's\" of the 'X' family just got a bit more big brother like.

With an intoxicating and menacing sound befitting of a high performance SUV the X3M\/X4M holds its own amongst the pantheon of more traditional M's. | In order to achieve the deep and throaty signature Dinan sound the system incorporates larger 76mm tubing (vs 70mm stock) that allows freer flow through the entirety of the system but specifically to both outer pipes when the enlarged valves are open. The resulting flow and sound mimics an awe-inspiring straight pipe solution with a deeper, fuller tone, a defining element of all Dinan exhausts. In contradiction to the aggressiveness resulting from open valves, when the valves are closed, all gasses are forced into the muffler for sound deadening and exit the two inner tips. Regardless of valve position, the intimate nature of the interior is retained so conversation can continue without an excessively loud drone courtesy of drone abatement technologies housed within the can. With the Dinan exhaust equipped on the X3M\/X4M you get the best of both worlds; aggressive tone\/sound and civility | Perhaps equally important to the sound of the installed Dinan axle back system are the resulting aesthetics. With a nearly perfect symmetrical design, the raw muffler and pipe routing are pleasing to the eye even when the matching proportions are only partially visible after install. The piping culminates into four massive 114mm (4.5\") tips that fill up the previously spacious factory cut out in the valance without appearing to be oversized and unnatural. The imposing tips utilize a new tip design with an inverted clamp neck. The new style allows for two very important things to happen. The first is the ability to have a longer tip sleeve length without sacrificing real estate for a clamp neck thus allowing larger tips even when there is limited straight pipe to clamp on to. Secondly, the interior clamp neck means that the clamp itself is almost completely hidden from view for an unblemished install. Dinan has retained its signature straight cut tip design, safeguarding its unique and elegant styling position amongst a crowded marketplace full of angle cuts. With systems available with either black ceramic coated or polished clamp-on, and laser engraved exhaust tips, there is a version that is sure to meet your individual aesthetic needs.\u003c\/p\u003e\n    \u003cp class=\"mt-2\"\u003eStainless Steel - Black Tips - F97\/F98\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003chr\u003e\n  \u003ch3\u003eFeatures\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cul\u003e\n      \u003cli\u003eMore Power: +8 HP @ 6600 RPM, +6 FT-LB @ 6600 RPM.\u003c\/li\u003e\n      \u003cli\u003eEnjoyably louder, sportier sound\u003c\/li\u003e\n      \u003cli\u003eQuad 4.5\" (114mm) diameter clamp-on, double-walled, black ceramic coated and laser engraved exhaust tips.\u003c\/li\u003e\n      \u003cli\u003eTuck-it tip design ensures a nearly flawless and unencumbered visual appearance.\u003c\/li\u003e\n      \u003cli\u003e100% 304 brushed stainless steel construction w\/ TIG welding.\u003c\/li\u003e\n      \u003cli\u003eLarger diameter piping for increased flow (76mm vs 70mm).\u003c\/li\u003e\n      \u003cli\u003e5 lbs lighter than the stock system.\u003c\/li\u003e\n      \u003cli\u003eComputer controlled exhaust valves retained, limiting noise during low speed driving and opening fully during high-load conditions.\u003c\/li\u003e\n      \u003cli\u003eTwin exhaust valves are a whopping 76mm diameter, making them 30% less restrictive than the OE valves.\u003c\/li\u003e\n      \u003cli\u003eEasy bolt-on installation with included mounting hardware.\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n  \u003ch4 class=\"mt-3 mb-1\"\u003eTECHNICAL SPECS\u003c\/h4\u003e\n  \u003cdl class=\"billy-specs\"\u003e\n    \u003cdt\u003eLength\u003c\/dt\u003e\n\u003cdd\u003e54\u003c\/dd\u003e\n  \u003c\/dl\u003e\n\u003c\/div\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":50548058849574,"sku":"D660-0086-BLK","price":1729.31,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/1666\/1542\/files\/D660-0086-BLK_1.jpg?v=1776354061"},{"product_id":"d660-0093","title":"Dinan Valved Axle-Back Exhaust - 2021-2026 BMW M3\/M4","description":"\u003cdiv class=\"billy_features_content\"\u003e\n  \u003ch3\u003eOverview\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cp\u003eThe G8x M3\/M4 is arguably superior in every category to its predecessor but in most, if not all, circles the biggest downfall of the platform is in the sound department.

The attention to detail is not limited to parts of the system you can't see once the exhaust is installed but is also extended to the exhaust tips themselves. The Dinan exhaust includes massive, quad 4.5-inch (114mm) clamp-on, double-walled, black ceramic coated clamp-on tips and laser engraved exhaust tips. Despite the seemingly cartoonish size on paper, the tips mesh seamlessly and fill the factory cut-outs to complete the OEM+ look with a healthy dose of audible attitude.\u003c\/p\u003e\n    \u003cp class=\"mt-2\"\u003eStainless Steel - Black Tips - G80\/G82\/G83\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003chr\u003e\n  \u003ch3\u003eFeatures\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cul\u003e\n      \u003cli\u003eMaximum gains of +6 HP and +5 lb-ft of torque\u003c\/li\u003e\n      \u003cli\u003eEnjoyably louder, sportier sound\u003c\/li\u003e\n      \u003cli\u003eDrone abatement technologies used to reduce cabin resonance\u003c\/li\u003e\n      \u003cli\u003eFour, diffuser filling, 4.5-inch (114mm) double-walled, black ceramic coated clamp-on tips with laser engraved Dinan logo\u003c\/li\u003e\n      \u003cli\u003eLarger diameter piping for increased flow (76mm vs. 70mm)\u003c\/li\u003e\n      \u003cli\u003e6-pounds lighter than the stock axle back (Stock: 44-pounds vs. Dinan: 38-pounds)\u003c\/li\u003e\n      \u003cli\u003eStock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings\u003c\/li\u003e\n      \u003cli\u003eComputer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions\u003c\/li\u003e\n      \u003cli\u003e100% 304 Stainless Steel construction\u003c\/li\u003e\n      \u003cli\u003eFactory-like fitment with included mounting hardware\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":50548066058534,"sku":"D660-0093-BLK","price":2029.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/1666\/1542\/files\/D660-0093-BLK_2.jpg?v=1776354380"},{"product_id":"d660-0096","title":"Dinan Valved Cat-Back Exhaust - 2020-2026 Toyota GR Supra 3.0","description":"\u003cdiv class=\"billy_features_content\"\u003e\n  \u003ch3\u003eOverview\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cp\u003eEvoke passion and excitement with the Dinan Valved exhausts for the GR Supra!

Not surprising given the latter model borrowing heavily from its older siblings' part catalog resulting in a wide swath of components being interchangeable amongst the trio. A few inlet pipe bends prevent the exhaust from being one of those but the M2 is still largely the same as the G8x M3\/M4 system. This allowed the extensive drone abatement development applied on those platforms to be used on the G87, fast tracking the R\u0026amp;D process. The result is the introduction of another member of G8x valved axle back exhaust family that elevates the tone to a deeper, more meaningful note while also delivering an extra level of amplification above and beyond its stock counterpart. | To achieve desired sound volume and tone worthy of the G87 M2 the tubing was enlarged to 76mm (vs 70mm stock) to allow freer flow, and reduce backpressure, throughout the entirety of the system. The larger piping gives way to multiple pathways as it nears the rear of the vehicle -- the choice of which is utilized determined by the factory exhaust valves which are retained. When valves are closed, flow is directed into the Dinan muffler, where absorption and reactive technologies are used, and exit out the two inner tips. This limits noise during low-speed driving and produces a more subdued, albeit deeper, and agreeable note. However, when the valves are open during high-load conditions the bulk of the gases bypass the muffler altogether for a near straight pipe design and maximum aural enjoyment to be achieved.

Not surprising given the latter model borrowing heavily from its older siblings' part catalog resulting in a wide swath of components being interchangeable amongst the trio. A few inlet pipe bends prevent the exhaust from being one of those but the M2 is still largely the same as the G8x M3\/M4 system. This allowed the extensive drone abatement development applied on those platforms to be used on the G87, fast tracking the R\u0026amp;D process. The result is the introduction of another member of G8x valved axle back exhaust family that elevates the tone to a deeper, more meaningful note while also delivering an extra level of amplification above and beyond its stock counterpart. | To achieve desired sound volume and tone worthy of the G87 M2 the tubing was enlarged to 76mm (vs 70mm stock) to allow freer flow, and reduce backpressure, throughout the entirety of the system. The larger piping gives way to multiple pathways as it nears the rear of the vehicle -- the choice of which is utilized determined by the factory exhaust valves which are retained. When valves are closed, flow is directed into the Dinan muffler, where absorption and reactive technologies are used, and exit out the two inner tips. This limits noise during low-speed driving and produces a more subdued, albeit deeper, and agreeable note. However, when the valves are open during high-load conditions the bulk of the gases bypass the muffler altogether for a near straight pipe design and maximum aural enjoyment to be achieved. It's the perfect marriage for all tastes and allows civility or impassioned aggression depending on what the situation demands. The combination is one Dinan has deemed fitting for the marques signature performance models that cater to the tasteful enthusiast who demand the best for all situations. | Visually, the Dinan G87 M2 exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color.

And from those aggressive-looking ceramic-coated tips flows an exhaust note that will be music to the driving enthusiast's ears. | The Dinan exhaust delivers exactly what the M3 owner demands in a performance muffler; increased power, reduced weight, a look that means business and the throaty exhaust note you'd expect from an M3.\u003c\/p\u003e\n    \u003cp class=\"mt-2\"\u003eStage 2 Engine Software recommended for optimum performance and drivability\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003chr\u003e\n  \u003ch3\u003eFeatures\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cul\u003e\n      \u003cli\u003eMore Power: + 7 HP @ 8000 RPM + 5 LB-FT @ 5000 RPM (w\/ software)\u003c\/li\u003e\n      \u003cli\u003eDrone abatement technologies used to reduce cabin resonance\u003c\/li\u003e\n      \u003cli\u003eEnjoyably louder, sportier sound\u003c\/li\u003e\n      \u003cli\u003eQuad 3\" black ceramic coated and laser engraved exhaust tips\u003c\/li\u003e\n      \u003cli\u003e15 lbs. lighter than stock (43 lbs. vs. 58 lbs.)\u003c\/li\u003e\n      \u003cli\u003e100% 304 stainless steel construction\u003c\/li\u003e\n      \u003cli\u003eUses the factory brackets and hangers for a factory-like fitment\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n  \u003ch4 class=\"mt-3 mb-1\"\u003eTECHNICAL SPECS\u003c\/h4\u003e\n  \u003cdl class=\"billy-specs\"\u003e\n    \u003cdt\u003eLength\u003c\/dt\u003e\n\u003cdd\u003e48\u003c\/dd\u003e\n  \u003c\/dl\u003e\n\u003c\/div\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":50548088144166,"sku":"D660-4604","price":1709.96,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/1666\/1542\/files\/D660-4604_1.jpg?v=1776354786"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/1666\/1542\/collections\/f6d2fa79f951591aa284d7e335920a57d9ddc003.jpg?v=1779182309","url":"https:\/\/billysspeedshop.com\/collections\/exhaust-systems-pipes.oembed?page=13","provider":"Billys Speed Shop","version":"1.0","type":"link"}
