Key Features
*Fits All G-Bodies except El Caminos - 118-inch Wheelbase Optional Adapter Pipes (sold separately): 70701317-RHKR - Use with Hooker Exhaust Manifolds The Hooker G-body exhaust systems have been verified to be compatible with factory OE and Hotchkis
This full stainless steel exhaust system comes complete with a stamped crossover for a broad torque curve and TIG welded stainless steel straight-through absorption style mufflers. It is dual 2.5-inch with a single turn-down exit under each quarter panel for a stealthy look. | Although these systems have been specifically developed for direct fitment with HOOKER™ LS swap components for these applications, they will provide equally beneficial fitment, function, and service life with other non-Hooker LS swap manifolds/headers. Can easily be made to work on non-LS engine-equipped G-bodies through modification of the system inlet tubes, or construction of new ones by a competent fabricator.
1978-1987 GM G-Body - 2.5-inch Dual Stainless Steel Natural Finish - *Fits All Except EL Caminos w/118-inch Wheelbase - Aggressive to Moderate Sound
- Each system is supplied with a high-efficiency stamped crossover & high-flow TIG-welded 304 SS absorption mufflers
- OE quality hardware (clamps, hanger rods and rubber isolators) provided to ensure excellent fitment and a leak free installation
- Kits are supplied with turn-down style exits under the rear quarter panels
- Stainless steel straight through designed absorption mufflers for a muscle car sound without the resonance
- Constructed of mandrel bent stainless steel tubing
- *Fits All G-Bodies Except EL Caminos - 118-inch Wheelbase
