Race Car Growl. This free flowing Magnaflow Tru-X X-pipe for the 1999 to 2004 Mustang's not only increases power, but with its modern "X" crossover pipe design it also adds a crisp raspy, race car growl to the sound of your exhaust.
Magnaflow High Flow Construction. Magnaflow uses free-flowing 2.5" mandrel bent stainless steel tubing that has a consistent diameter throughout the entire length of the pipe, even at the bends to provide excellent exhaust flow that results in more power at the rear wheels.
Application. This Magnaflow Tru-X Off-road X-pipe is designed as a direct bolt-on for the 1999-2004 GT, 2001 Bullitt, 2003-2004 Mach 1 and 1999-2004 SVT Cobra with either aftermarket short tube headers or the stock factory manifolds and a dual catback exhaust installed. Intended for off-road, track use only, does not include catalytic converters.
Technical note: 2004 Mustangs require the use of 24" O2 sensor plug-in extender wires. This Magnaflow product is intended for off road use, and is not legal for use in emission restrictive states.
