American Racing Headers



Long Tube Exhaust Headers for Right Hand Drive

Ford Mustang 5.0L GT V8 2015-18

Manufactured by American Racing Headers

Available in 1 3/4" or 1 7/8" Long Tube Headers with High Output Cat.

ARH RHD Headers were exclusively developed in the UK on the Nemesis UK Project Mustang 5.0L GT with the help of Modurstang at their garage in Chipping Norton. The ARH team flew over from their headquarters in NY USA with their tool and components to fabricate specific headers for the UK's RHD Mustangs to ensure the perfect fitment!


  • By using proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most "Check Engine Light" issues
  • Capable of withstanding up to 1500 deg F
  • Ideal for forced induction applications, with no loss of HP

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.
