This Borla exhaust system offers a great dual exhaust system for the 400-horsepower 2005-06 Pontiac GTO.

Like current versions of the new Corvette C6, the BORLA (PN 140165) GTO Cat-Back includes a proprietary BORLA X-Pipe that merges to smoothly blend the powerful V8 exhaust pulses that assist in both performance and sound attenuation. The full direct bolt-on mandrel bent 2.5" T-304 Stainless Steel Cat-Back is over 25 pounds lighter than stock while flowing over 200cfm more air, accounting for the dramatic performance and mileage improvements. The split rear exit through large 5" polished rolled round angle cut tips proclaims this new GTO means all business.
