Make your Mustang rumble with this stainless steel cat back from Borla.

The 140135 is lighter than the factory system and significant increases 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.

BORLA, the original pioneers of aerospace-grade T-304 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. Unsurpassed written million-mile warranty.

Although these Borla exhaust systems weigh between 45-65 lbs, Fast Mustang Parts ships these at a 30lb discounted weight.
