Borla 11750 - S-Type Axle-Back Exhaust System 2005-2009 Ford Mustang GT 4.6L V8/ 2007-2009 Ford Mustang Shelby GT500 5.4L V8 Supercharged Automatic/ Manual Transmission Rear Wheel Drive 2 Door Coupe/ Convertible.

For over 4 decades, Borla Exhaust has been the choice of Mustang experts, from the Cobra-R SVT Mustang to the Ford GT. 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 awesome Axle-Back system bolts on, is lighter than the factory system, includes our famous S-Type mufflers with outstanding flow numbers that generate great power enhancements, and features bright chrome on T-304 stainless steel tips. These attributes, coupled with an aggressive sound of power and awesome big tip, proclaim this Stang is all business. Airflow management and exhaust engineering is a science with which Borla has more experience than anyone in the exhaust aftermarket. The performance matches the famous Borla systems of the past but with a unique muffler and exhaust configuration canceling additional high frequency sound waves. Delivering a significant increase in CFM from the factory system which, as most engine builders will confirm, accounts for the dramatic power improvements. Perhaps more importantly, this added flow maximizes performance for other aftermarket enhancements installed on the Mustang because all Borla exhaust products are tuned for maximum output from any aftermarket performance upgrade. Two Axle-Back options are also available: an aggressive S-Type (PN 11750) and a more mellow Touring (PN 11752) both replace only the over-the-axle pipes, mufflers and tips. Borla, the original pioneers of 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.
