Corsa Sport Cat-Back Exhaust System w/ Oval Tip - 2004 Pontiac GTO


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.

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.
