Review & Install Video

Hey everybody. I'm Justin with AmericanMuscle.com, and this is my review of the MAC Pro Chamber Catback Exhaust System available for your 2015 and up Mustang GT. So, the MAC Catback Exhaust System is going to be for any S550 GT owner out there who is looking to add some more sound, maybe even a little bit more performance to their ride, but without totally wiping out their bank account in the process. Make no mistake about it guys this is a valued Catback Exhaust System, with only the MVRP systems coming in a little less expensive than the MAC. As a result don't expect the same quality or tone as you might get with those more expensive 12 or 13 hundred dollar systems. Sticking with quality here for a little bit guys, I'll be the first to admit this isn't exactly the prettiest exhaust system I've ever seen in my life here. It's a little unfinished at parts. The welds are a little chunky, a little sloppy here. The tips look like they were just slapped onto the mufflers. It's a little rough, and I think that that's a good way to put it, but overall I feel like MAC wears that as a badge of honor. With that being said though, however, this is an exhaust of course so it is going to live underneath the car for most of its life, if not all of its life. So, you'll probably never even see half this stuff minus the tips, and it is about sound ultimately. As you heard at the beginning of this video guys, the sound definitely delivers. Now I know we throw the term muscle car sound around a lot here, but I feel like the Pro Chamber really does embody that. A big portion of that muscle car sound can definitely be attributed to here the MAC H Pipe, or MAC Pro Chamber H Pipe. It is going to deliver that lower rumble, as opposed to the high pitched rasp of an X Pipe, and it's a sound a lot of you guys might prefer over that X Pipe design. Ultimately not the loudest exhaust system I've ever heard, so for that reason alone we'll give it a strong two, maybe even a three out of five on the one to five, or one to wake the neighbors scale. But overall it definitely produces a solid tone. Getting into some of the finer details. Here with the MAC system you'll find 100% stainless steel for the construction. You're going to be looking at two and a half inch mandrel bent tubing throughout. Of course the included Pro Chamber mid pipe here. The flow pack chambered mufflers all exiting out the large 4 inch polished tips. Now guys, as for the install, again, not to bad here with any install for a Catback Exhaust System for your 2015. If you haven't seen the video by now expect a one out of three wrenches on the overall difficulty meter. Overall not bad thanks to the independent rear suspension. An extra set of hands might help getting this thing in place, but expect about an hour or two underneath the car. So for that reason of course you're going to want your jack and jack stands on hand, maybe a set of race tramps if you have them, and a few basic hand tools. While I might not be the biggest fan of this exhaust, from the looks down to the overall build quality it certainly delivers where it needs to, and that is giving your S550 GT that classic muscle car rumble for a price that's far lower than most other options on the site. So be sure to check out a MAC Pro Chamber Catback for your 2015 and up GT right here at AmericanMuscle.com.

Improves Performance and Sound. Add a throaty muscular exhaust note to your coyote powered GT Mustang and improve it's performance at the same time with a MAC Performance Cat-Back Exhaust System. By reducing back pressure with a free-flowing exhaust, you will see rear wheel gains in both horsepower and torque.

Muscle Car Rumble. The included MAC Performance Mid Pipe not only increases the horsepower and torque of your S550 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 stock factory "resonator" just can't match.

Flow Path Mufflers. MAC Flow Path Chambered Mufflers feature a patented multi passage design, following Helmholtz's Theory of Tone, to produce a muffler that effectively flows exiting exhaust gases all while maintaining a desirable tone. With no packing that can burn out, Flow Path Mufflers will sound the same mile after mile, year after year.

High Quality Construction. Constructed from mandrel bent stainless steel tubing for superior strength and corrosion resistance, this MAC Performance Mustang Cat-Back Exhaust System features two "Flow Path" chambered mufflers that end with massive 4" diameter polished stainless steel slant cut exhaust tips for impressive muscle car looks and sound.

Direct Bolt-On Install. The MAC Performance Cat-Back Exhaust with Pro Chamber Mid Pipe includes all the hangers and clamps necessary to bolt straight up in the OEM factory location without any modifications required, making it a direct fit, bolt-on replacement upgrade.

Application. This MAC Performance Cat-Back Exhaust with Pro Chamber Mid-pipe is specifically designed to fit all 2015-2017 GT Fastback Mustangs equipped with the 5.0L 4V coyote engine. Not compatible with convertibles.

    Exhaust fit nice but the Clamps are junk... do your self a favor buy four Quality 2 1/2 inch V band clamps off eBay. The clamps that come with exhaust R not strong enough to squeeze the flanged pipes togeather
