Product Overview

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 awesome Cat-Back system bolts behind the factory H-pipe, is lighter than the factory system and includes our famous "S-Type" mufflers (PN 140135). X-Pipe (PN 60092) may be added to this system. Borla experience and advance engineering have produced a sexy "S-Type" exhaust with outstanding flow numbers that generate great power enhancements. These attributes, coupled with an aggressive sound of power and awesome big bright chrome on T-304 stainless steel tips, 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 system 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 premium, 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. Best of all, each system come with the unsurpassed Borla Million-Mile Warranty.
