    See Emissions Details
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.

Features:

  • 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
