American Racing Headers 1 7/8" x 3" LT's "Long System W/ Cats" 18+ Mustang GT
* Note: these will work on 15-17 with the correct extensions.
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. 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.
