Borla® (04-06) Pontiac GTO 304SS 2.5" S-Type Cat-Back System

S-Type Classic sound. BORLA® Performance Industries offers a great dual exhaust system for the Hot 400-horsepower 05-06 Pontiac GTO Super Cruiser. The coupling of the Chevrolet LS2 Corvette V8 and the Tremec 6-speed transmission (or 4 speed auto) has made this “Tin Indian” a noble warrior. The Pontiac Tempest V8 GTO arguably was one of the first Pony cars of the 60‘s. Pontiac, the famous Ottawa Indian Chief that roamed the old Fort Detroit area 250 years ago, would be proud of how his legend has been carried forward.

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 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 exhaust gasses 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” bright chrome on T-304 stainless steel 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.
