BORLA has a long standing reputation of working with Pontiac racing efforts, engine builders and hot street cars. This legacy, combined with BORLA's involvement with the Corvettes, makes a perfect combination for a fantastic street system. 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 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.
