Description
Borla S-Type Classic Cat-Back Exhaust System for 2005-2006 Pontiac GTO 6.0L V8 Automatic/ Manual Transmission Rear Wheel Drive 2 Door Coupe. (140165)
Upgrading your factory exhaust system to a Borla stainless steel performance exhaust system with a more efficient and less restrictive design can improve sound (adding more enjoyment driving your vehicle) and increase engine horsepower and torque throughout the RPM range (allowing quicker acceleration to pass a vehicle or get to highway speeds quicker). Borla offers Axle Back exhaust systems, Cat back exhaust systems, and for select Competition-Use-Only vehicles, we offer long tube headers to replace your exhaust manifold for the best performance and sound.
The Borla “Cat Back™” name implies the exhaust system is located behind the factory catalytic converter where there factory emissions remain untouched and vehicle stays emissions compliant. This remains distinct from the Axle Back exhaust system that is located behind the rear axle. Alex Borla coined the phrase ‘Cat Back’ and introduced the Cat Back performance exhaust in 1978, a bolt-on replacement performance exhaust system requiring no welding, thus being secured using the factory hanger locations.
Borla Cat Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle. Borla Cat Back systems increase the overall sound level & performance. Vehicles that don’t have a factory service-point require “cutting” the factory exhaust system before installing a Borla Cat Back performance exhaust system. Borla includes instructions where to make this cut and includes the hardware to complete the installation. Many of today’s modern vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the catalytic converter. A Borla Cat Back performance exhaust system replaces the factory exhaust system (behind this service-point) following the same exhaust path and secured using the original vehicle hangars and rubber isolators. Borla pioneered the automotive exhaust aftermarket in exhausts constructed in aircraft grade 304 stainless steel tubing, a material with higher content of carbon & nickel that won’t rust or corrode.

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’ once again 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 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.
