Optional Adapter Pipes (sold separately): 70701317-RHKR - Use with Hooker Exhaust Manifolds Requires double hump style crossmember (i.e. 12644HKR or 12644HKR-1) since the factory unit does not have clearance for dual exhaust.
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 3-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.
