Manufactured by American Racing Headers | Part #MTRHD-15134300LSWC
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 anaemic factory exhaust.
With ARH header systems in 1-3/4" and a 3" exhaust, the 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, for a more classic muscle car sound.
IMPORTANT: American Racing Headers Exhaust Systems are for OFF-ROAD use only.
