This Borla SwitchFire X-pipe replaces the Merge X-pipe in Borla 3in cat-back systems for the Mustang GT and Dark Horse. The patented SwitchFire design eliminates the turbulent center intersection of a standard X-pipe to blend the combustion pulses from both banks, yielding an aggressive custom sound and improved power. A hydroformed center section gives it a lower profile. T-304 stainless steel; reuse the clamps from the Borla Merge X-pipe (clamps not included). Use with Borla cat-back systems only.
