Product Details

---

Owners of the 2004 GTO can now attain that muscle car era sound while enhancing the performance of their Goat with an exhaust system from CORSA. Utilizing patented* Reflective Sound Cancellation (RSC) technology, the CORSA exhaust delivers a full-bodied aggressive sound during hard acceleration and a quiet resonance-free note at cruising speeds  an ideal complement for the GTO's 350 horsepower, V-8 engine.

CORSA offers two GTO exhaust designs; the RSC Sport, for drivers wanting a more aggressive, throaty exhaust tone, and the RSC Touring, producing a distinctive, strong sound. A choice of the 4-inch Pro-Series tip or the CORSA GTO Oval tip (both doublewalled stainless steel construction) are available for either system. Crafted in the U.S.A. from 3-inch 304L stainless steel, CORSA Performance Pontiac GTO exhaust systems are lighter than stock and guaranteed for original ownership of the vehicle.
