‘07-'08 Shelby GT 500 Mustang Gets Full Treatment from BORLA Aggressive BORLA Cat-Back and a Long Tube Competition Header Oxnard, California – BORLA Performance Industries owner, Alex BORLA, has a star-studded history with Ford legends like Carrol Shelby, who chose BORLA for his 427 Cobra continuation series, just as Ford SVT chose BORLA for the Cobra-R Mustang. BORLA RD engineers have designed a complete package for this new GT500 Shelby Mustang super car, starting with a tuned Cat-Back exhaust (PN140210) incorporating unique, genuine BORLA race-bred brushed satin S-style straight-through mufflers that create more flow, weigh considerably less than stock and have that incredible bold BORLA signature sound. Testing has shown power increases above 20 horsepower alone. BORLA has taken its racing experience and designed a custom 1-¾” full length competition header (PN17238) for the Shelby that is an engineering performance benchmark: Expensive, high quality austenitic stainless steel is the foundation for the quality header this car demands, and BORLA worked with top race teams to design a header that not only is lightweight, makes exceptional performance, but is also ingeniously designed for chassis fit. Modeled after the successful Ford GT and Mustang GT header, PN17238 allows straight forward installation and the ability to work on the car (like clutch and starter) without removing the headers. Serious competitors know what a critical time saving that is at the track. BORLA has a 30-year tradition of building performance exhaust for high end performance machines and is the original pioneer of high quality, austenitic stainless steel (superior to 409 or aluminized steel) free-flow, CNC mandrel bent exhaust. Patented award and race winning technology delivers quality, sound, performance gains and enhanced fuel economy -- all with an easy bolt-on installation and backed by an unsurpassed written million-mile warranty.
