Increase Exhaust Flow. Get rid of those power robbing factory catalytic converters and uncork your V6 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 V6 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. Constructed from durable 2.5" diameter stainless steel tubing, this MAC Performance mid pipe is CNC mandrel bent to ensure maximum exhaust flow, so there are no kinks to rob you of power.

Application. This MAC Performance Pro Chamber Off-road Mid-pipe is designed as a direct bolt-on for the 2011-2014 3.7L V6 Mustangs with either aftermarket short tube headers or the stock factory manifolds installed. Intended for off-road, track use only, does not include catalytic converters.

Please Note. Stock 2011 V6 Mustangs come stock with a mid-pipe that resembles both the H-pipe and X-pipe designs. This hybrid mid-pipe was created by Ford to help add additional power and sound to the V6 straight out of the factory. This MAC aftermarket mid-pipe will further help you reach maximum air-flow equaling additional power.

Answer This Question

Do you have a sound clip? Your info page about Xpipe vs Hpipe said the exhaust pages are supposed to have sound clips.

    Mac off road pro chamber

    This mid pipe is quite the beast. It comes all shined up in the box. Weighs 23 pounds. Install took less than 4 hours with 2 people and about 1 1/2 foot of extensions. The box hangs down about 2 inches lower so watch out for speed bumps and driveways. Now for the tone. I have flowmaster 40 series welded in for my axlebacks, which are already raspy. If you putt putt around town under 2500 rpm it sounds the same as if you had cats. If you get on it, it'll wail. A lot of off road pipes have a harsh rasp at 3000 rpm. As does this one, yet, it's not as bad. It's deeper, has more bass, and more power than the H. I highly recommend this mid pipe because it still sounds like a stock setup until under heavy throttle. Very sleeper like. The bass on startup will shake your chest.
