Product Details

The American Thunder Cat-back exhaust system for 2011-2018 Chevrolet Silverado and GMC Sierra 1500 trucks with the 6.2L engine, is perfect for the person looking for an aggressive exterior sound level while maintaining a moderate interior tone. This bolt-on stainless steel system features a 3.50-inch mandrel-bent inlet pipe flowing into the 50 Series HD performance muffler with large 4.00-inch internals and a built-in tuned resonance chamber to minimize interior drone. The system has dual 2.50-inch mandrel-bent tailpipes which use the factory hanger locations and are finished off with large 3.50-inch polished stainless steel tips. This exhaust system gives you choices for tailpipe exit location either out each side behind the rear tires if you do a lot of towing, or straight-out under the rear bumper for a muscular look. The exhaust system is covered by our Lifetime Limited Warranty and includes all necessary parts and hardware for easy installation you can do at home. Note: Fits 2/4 WD model with Extended Cab standard bed and Double Cab with 5.5-ft bed.
