ARH RHD GT Long tube headers
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, this Direct Connect Kit unlocks that power with performance gains up to 30 RWHP.
Designed to work for Stock Catback Systems, without any cutting or welding. If you are in the market for a Catback as well, consider the ARH Full System, 3" X-Pipe and our Pure Thunder series mufflers.
