S-Type Classic sound. BORLA Performance Industries offers a great dual exhaust system for the Hot 400-horsepower 2005-2006 6.0L Pontiac GTO.
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 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 high quality austenitic 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 GTO means all business. BORLA, the original pioneers of aerospace-grade high quality T-304 austenitic stainless steel (superior to 409 or aluminized steel) free-flow exhaust utilizes patented award and race winning technology to deliver quality, sound, performance gains and enhanced fuel economy ? all with an easy bolt-on installation and backed by an unsurpassed written Million-Mile Warranty.
