Description
Increase Exhaust Flow. Ford did a decent job on their new catalytic converters, but the stock H-pipe is pretty restrictive. That's where the MAC Performance After Cat Mid-Pipe comes into play. Featuring MAC's unique Chamber style crossover and free-flowing mandrel-bent piping, this mid-pipe will dramatically improve exhaust flow for more power and sound.

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

Compatible With Stock Cats. The MAC Pro Chamber Mid-Pipe bolts up directly behind the stock factory catalytic converters with no cutting required saving you time and money. By reusing your stock catalytic converters you ensure that Mustang is smog-legal.

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. The MAC Performance Pro Chamber Mid-pipe is designed to be a direct bolt-on for the 2011-2014 5.0L GT Mustangs with either aftermarket short tube headers or the stock factory manifolds installed. Reuses the stock Catalytic Converters.

I really like the sound of the prochamber. It is nice an deep and smooth. I wasnt sure what it would sound like because although they are out of stock a lot, I couldnt find videos of them on the new models.

    I really like the sound of the prochamber. It is nice an deep and smooth. I wasnt sure what it would sound like because although they are out of stock a lot, I couldnt find videos of them on the new models. I have the GT500 axlebacks with resonator delete and it sounded mean. BUT the prochamber made it so quiet now I can barely hear my car. Good product, but I HIGHLY RECOMMEND making sure your mufflers are loud. The prochamber will cut the volume in half. As for power gains. Couldnt tell a thing. I can tell you it drives smooth and sounds good from the outside, but if your a guy who likes to hear it when they drive, be careful what axlbacks you run.

    Best H pipe

    This is the second Mac pro chamber I've had and they are definitely worth the money. Average RWHP gain is 23, the figures are on MAC website. The sound is great however, I noticed it did quiet down my Kooks axle backs a little bit. The sound that followed though was a clean crisp muscle car rumble with little to no drone. If your hesitant about this H-pipe cause you don't want to sacrifice sound for power then I'd say delete that cats and you will get the sound back not to mention HP. That's what I did now the sound and power are spot on. All together this is a great product that is well made and puts out great power and sound. Install is straight forward and can be done in less than an hour with some jack stands and a wrench.

    2013 5.0 bigboy

    This is a good h pipe. Very good increase n power that u can feel. With 22 rims the car will spen the tires in 2rd from just hard throttle. I have hushpower mufflers that sounds good with stock h pipe but this h pipe quiet it down alot but a good trade for me less sound more power. May try a different muffler to increase sound back to were it was. Roush or flowmaster outlaw. Diff worth the money.
