Borla Cat-Back S-Type Dual Exhaust (140135) boosts flow and aggressive sound for 2005–2009 Mustang GT with premium T-304 stainless steel construction.
This high-performance Cat-Back exhaust system from Borla is engineered for 2005–2009 Ford Mustang GT models. It bolts directly behind the factory H-pipe, replacing the stock system with a lighter setup featuring Borla’s signature "S-Type" mufflers. Constructed from T-304 austenitic stainless steel, the system ensures superior corrosion resistance and long-lasting durability. Enhanced flow and reduced back pressure allow for increased horsepower and torque, especially when paired with other aftermarket upgrades. The exhaust note is deep and aggressive, delivering a track-inspired sound that reflects the Mustang’s performance pedigree.
