BBK Competition Series Off-Road X-Pipe (99-04 4.6L)
Increases Overall Performance. Add even more horsepower and torque to the rear wheels by eliminating those power robbing catalytic converters with a BBK Off-road X pipe. A BBK X pipe will greatly improve your pony's exhaust flow to increase overall performance and sound.

Race Car Growl. A free flowing BBK x-pipe not only increases power, but it also adds a crisp raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

Durable BBK Construction. This BBK direct replacement X-pipe features 2.5” diameter CNC mandrel bent aluminized tubing and a merged X crossover to improve exhaust flow. Additional features include factory O2 sensor locations, and OEM style die-stamped flanges all to ensure a perfect fit.

Application. Specifically designed to fit the 1999 to 2004 4.6L Mustangs, including the GT, Bullitt, Mach 1 and SVT Cobra. This Off-Road X-pipe is a direct fit replacement for the stock mid pipe.
