Improves Performance and Sound. Give your 3.7L powered S550 Mustang an aggressive exhaust note, while improving its performance at the same time with a MAC Performance Cat-Back Exhaust System. Not only does this MAC Exhaust System sounds great, but the included x-pipe improves the exhaust flow to reduce back pressure, which provides an increase in horsepower and torque at the rear wheels.

Race Car Growl. The included MAC Performance X-Pipe not only increases the horsepower and torque of your S550 Mustang, but it also adds a crisp raspy race car growl to the sound of your exhaust with its modern "X" crossover pipe design - a sound 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 X-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 X-Pipe is specifically designed to fit all 2015-2017 V6 Fastback Mustangs equipped with the 3.7L V6 engine. Not compatible with convertibles.

The exhaust is great, it gives that muscle car tone to your v6, its loud and agressive, so i personally love it. However, it has too much drone and i believe this is due to the muffler systems. You can ...

    Drone!

    The exhaust is great, it gives that muscle car tone to your v6, its loud and agressive, so i personally love it. However, it has too much drone and i believe this is due to the muffler systems. You can barely have a conversation inside the car and i mean this when cruising; it gets really annoying. The exhaust tips also stick out about 2" compared to the stock tips. But keep in mind this is an $800 exhaust and almost none other come with an xpipe for your v6.

    Serious sounds

    For the price you can't beat it. After reading the reviews and looking around I decided to try this cat back. Definitely in love. Took a shop about an hour and a half to install. The clamps aren't very great though and the was some play in the exhaust at the fittings so the shop welded it in those places. It has a nice deep tone. It is quite loud inside as of now. Not sure if the drone will go away after a while or if I'll just get used to it but for the price you really can't beat it. MAC definitely did it right.

    Sound good once they have broken in

    Had this cat-back installed at Midas and they had no issues getting this installed and aligned within 45 minutes. The mechanic actually said this kit was the best fitting he had seen so far on the new Mustangs. After about 500 miles the drone on these calmed down quite a bit. The drone is almost completely gone now that I have an Airaid Cold Air Intake installed. Nice throaty exhaust note.
