Borla Stinger Catback Exhaust (Aggressive) – 2005-2009 Ford Mustang GT – 140135

This system features Borla’s Stinger straight through Bullet mufflers for an aggressive tone and great flow! For nearly 3 decades, Borla Exhaust has been the choice of Mustang experts, from the Cobra-R SVT Mustang to the new 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 . And, when the �05 Mustang was first being reviewed, Borla was already busy designing an awesome new Cat-Back� system that bolts behind the factory H-pipe, is lighter than the factory system and includes our�famous �S� Style mufflers (PN 140135). Borla experience and advance engineering have produced a sexy new �S� Style exhaust with outstanding flow numbers that generate great power enhancements. 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 rear section options are also available: an aggressive �S� Style rear exhaust section (PN 11750) and a more mellow rear section (PN 11752) � both replace only the over-the-axel pipes, mufflers and tips. Borla , the original pioneers of aerospace-grade high quality 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.
