Borla Cat-Back Dual Exhaust System for 2005-2009 Ford Mustang GT
Borla Cat-Back Dual Exhaust System for 2005-2009 Ford Mustang GT
For over 4 decades, Borla Exhaust has been the choice of Mustang experts. Major players in the racing industry and leading tuners from Roush, Steeda, Saleen, and Ford Racing to the Shelby 427 Cobra have relied on Borla. This exceptional Cat-Back system bolts directly behind the factory H-pipe and is lighter than the factory system, featuring our renowned "S-Type" mufflers (PN 140135).
The Borla experience and advanced engineering have produced a sleek "S-Type" exhaust with outstanding flow numbers, generating impressive power enhancements. These features, combined with an aggressive sound that exudes power and bright chrome finishing on T-304 stainless steel tips, firmly establish that this Mustang means business.
Airflow management and exhaust engineering are a science, and Borla has more experience than anyone in the aftermarket. The performance attained matches the legendary Borla systems of the past, but with a unique muffler and exhaust configuration that effectively cancels additional high-frequency sound waves. The system delivers a significant increase in CFM from the factory, leading to dramatic power improvements, which many engine builders can attest to.
More importantly, this enhanced airflow maximizes performance for other aftermarket enhancements installed on the Mustang, as all Borla exhaust products are fine-tuned for maximum output with any performance upgrades. Additionally, two Axle-Back system options are available: an aggressive "S"-Type (PN 11750) and a more mellow Touring (PN 11752), both of which replace only the over-the-axle pipes, mufflers, and tips.
Borla is a pioneer of premium, high-quality T-304 austenitic stainless steel, which is superior to 409 or aluminized steel. Our free-flow exhaust utilizes patented, award-winning technology to deliver quality, sound, performance gains, and enhanced fuel economy—all with easy bolt-on installation. Best of all, each system comes with the unparalleled Borla Million-Mile Warranty.
