Stock 2015 Mustang GT exhaust next to Ford Performance by Borla Touring MufflerHere we see the new USA-made Ford Performance by Borla M-5200-M8TBV Touring Exhaust System next to the factory exhaust.
Ford Performance by Borla Touring MufflerThe Ford Performance mufflers are manufactured by Borla and feature a “Y” pipe that feeds all four exhaust tips in the GT350 lower valence at all times. By comparison, the GT350 utilizes an active exhaust that has a valve that closes to make the exhaust flow through more of the muffler and out of the outer tips to quiet the sound in normal mode. The valve then opens during sport mode for a more direct and louder exhaust out of the center tips.

FP bends vs stockThe Ford Performance Exhaust comes in three main pieces. This mid-section connects the X-pipe to the muffler. Note the smoother 2.25” mandrel bends compared to the more restrictive factory exhaust bends.
