    Description

    Increase Exhaust Flow. Get rid of those power robbing factory catalytic converters and uncork your Mustangs hidden power with a MAC Performance Off-road Mid-Pipe. Featuring their exclusive Pro Chamber style crossover and free-flowing mandrel-bent piping, this high performance Mid Pipe will dramatically improve exhaust flow for more horsepower and torque.

    Aggressive Muscle Car Rumble. This free flowing MAC off-road Mid Pipe not only increases the horsepower and torque of your Mustang, but with its unique Pro Chamber cross over design it adds a more aggressive muscle car rumble to the sound of your exhaust, that the standard H-Pipe just can't match.

    High Quality Construction. Mandrel bent from durable 2.5" steel tubing so there are no kinks to rob you of power, this MAC Performance Mid Pipe has been hot-dip coated with aluminum-silicon alloy to aluminize the steel to protect against corrosion and rust.

    Application. This MAC Performance Pro Chamber Off-road Mid-pipe is designed as a direct bolt-on for the 1999-2004 4.6L Mustangs, including the GT, Bullitt, Mach 1 and SVT Cobra Models with either aftermarket short tube headers or the 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 MAC Performance product is intended for off road use, and is not legal for use in emission restrictive states.
