The latest generation of Mustangs brought performance and handling to a whole new level, but power and torque as still waiting to be unleashed from an anemic factory exhaust. With header systems in 1-3/4″, 1-7/8″ or 2″ (for max effort applications) and a 3″ exhaust, our Long System unlocks that power with performance gains up to 30 RWHP.
A simple mark and cut (no welding required) mates the ARH Long System to your existing Axelback. Comes with a 3″ X-Pipe standard or optional H-Pipe, for a more classic musclecar sound. The video below was shot with an X-Pipe equipped Full System with ARH Pure Thunder mufflers. Sound may vary depending on mufflers used. Consider upgrading to the Full System if you like the sound.
