    Bold Sounds. This MAC 3 in. Cat-Back Exhaust will give your Mustang the throaty rumble you expect out of an American muscle car. The 3" diameter flows much better than stock, and the packing-free multi-chamber muffler is tuned to deliver the sound of performance. MAC knows how to make your Mustang sing, and all without that dreaded highway drone.

    Powerful Performance. MAC tunes this exhaust to flow better than stock. That means noticeable improvements in power, torque, and throttle response. If you can withstand the overwhelming temptation to floor it from every intersection just to hear that magical roar, your fuel mileage might even improve.

    Stainless Steel Construction. MAC uses 100% stainless steel in this cat-back. Those all-mandrel-bent curves are polished to a high luster. The stainless will never rust, corrode, or fade. The muffler is a multi-chamber design that doesn't rely on packing to soften the volume. That means sonic characteristics won't change through time and wear. No packing, no problem. The 4" diameter stainless tips are real, and they are fabulous. This system is built to last, and provide joy mile after mile for the life of your 'Stang.

    Bolt-On Install. MAC includes everything you need to get the most out of your Mustang's exhaust tract. No welding, cutting, or fabrication is needed. Follow the easy step-by-step instructions. All necessary hardware is included.

    Application. This MAC 3 in. Cat-Back Exhaust fits your 2011 through 2014 GT 5.0L Ford Mustang.

      Deep Sound!

      Very deep sound when first started and then mellows out nicely. Deep revs similar to the gt500 but, more beastly. Sounds awesome cruising around with a deep tone under 3500 rpms. After 4500 rpms, the sound isn't very loud and not a deep tone anymore. It then starts to sound like an old 5.0 with Flowmasters after 4500 rpms. The exhaust also tends to start popping on deceleration around 2000 rpm. It can be heard from several hundred feet away. It depends on what you're looking to achieve for sound. Sounds like a beast when cruising and doesn't grab TOO much attention when doing pulls. Great to stay under the radar. Plus you can hear the blower whine just fine, which is cool too
