Key Product Specs
  • MAC's Off Road Prochamber pipe offers a unique design not found in any other mid pipe. This unit is a complete bolt-on replacement for your restrictive catalytic converter stock setup. The unique Prochamber produces more horsepower and torque over any conventional Mustang H or X mid pipe.

  • Not only does the Prochamber give you more power, but its unique design produces an intoxicating exhaust note. If you've already installed an aftermarket catback and are not happy with the sound, this prochamber unit will fix the problem! Not only will it give you that signature Mustang sound, but it will also increase horsepower and torque dramatically. The off road design flows much better than the restrictive H pipe. You will notice easier acceleration on the street and lower quarter mile times at the dragstrip.

  • 2.5 inch design
  • Free flowing off road design
  • Features aluminized tubing for long lasting design

    Fits all 1999-2004 V8 Mustangs including the Mach 1, GT, Bullitt and Cobra model
    Fitment note - o2 sensors are required when installing on 2003-2004 models

Mac off road prochamber. 99-04 v8 June 10, 2013
Reviewer: Kevin Dungan from Paramus, NJ United States  
This mid pipe sounds great. It sounds best on the 4valve due to the added rasp and deep rumbly  tone. The prochamber is the perfect tone between x and h. I like the deep tone of the the h, and rasp of the x and this is the perfect mixture. The only problem I had was a dent on one of the donut flanges but I welded and painted it and now it is leak free. If for some reason I bought another mustang I would install tgismid pipe again. This midpipe is also slightly quieter than the average off road x so I can keep the neighbors slightly happy at 3am.

Race quality February 28, 2013
Reviewer: JonnyReb from Martin, GA United States  
This arrived just as it was listed and shown. Designed for race, the overall finish is nothing fancy. But this is designed for performance, and it follows through. Due to the appearance I give this 4 stars, but I am satisfied completely.
