Borla SwitchFire X-Pipe Upgrade - Ford Mustang GT 2018-2023 (for Borla Cat-Back)

The Borla SwitchFire X-Pipe replaces the Merge X-pipe in Borla Cat-Back systems 140742, 140745, and 140746 (including the Black Chrome and Carbon Fiber tip versions) on the 2018-2023 Ford Mustang GT. It is designed to work with those Borla cat-back systems only. Borla's patented SwitchFire design eliminates the turbulent center intersection of a standard X-pipe to blend combustion pulses from both banks for an aggressive sound and improved power. Built from T-304 stainless steel with mandrel bends and CNC fit, and backed by Borla's Million Mile Warranty. Includes two adapters (2.25 inch ID inlet to 2.75 inch ID outlet, 5 inch long) and four clamps.
