Borla Cat-Back Exhaust - Ford Mustang GT (S550) - Touring 2.5in 2015
This Borla cat-back exhaust suits the 2015 Ford Mustang GT (S550) and replaces the factory system from the catalytic converter back. The 2.5in system has a resonator with an internal H-pipe and exits through 4in tips in polished or black chrome. It delivers Borla's Touring sound, the mildest level, tuned to avoid drone in the cabin.
Note: Borla lists this system for 2015 models. Care tip: stainless steel polish is not recommended on the black chrome tips. Designed around the US left-hand-drive Mustang. The underbody layout is shared with the factory right-hand-drive Australian Mustang, so cat-backs generally fit, but please confirm valance and tip cut-outs and active exhaust fitment with our team before ordering. Installation by a professional is recommended.
