1997-04 C5 and Z06 Dominator GT Pro & GT Race Exhaust System This is an Aft-Cat system designed to replace the dual mufflers at the rear of the car with our revolutionary single center- mount muffler which incorporates the famed X? into the muffler itself (muffler in tunnel location). The performance increases and weight savings of this system are superior to dual-muffler systems. Features 2½" mandrel bent stainless steel tubing and comes complete with superior quality mounting hardware and detailed instructions. The GT Pro is aggressive on acceleration, yet mild at cruising speeds minimizing cabin resonance. The GT race version is a much more aggressive system, for the one who wants to make a statement.Backed by a LIFETIME WARRANTY and legal in all 50 states. Choose from our standard 4" polished slant cut, or optional 4" polished billet insert tips. Power gains of 14-16 HP and 16-18 ft lbs torque. |
