The MAC Catback Exhaust with Pro Chamber is an affordable way to add some additional noise to your 2015-2016 V6 Exhaust. This MAC exhaust will increase exhaust flow while maintaining a louder exhaust note. ****** Improve Performance and Sound. Improve the power of your 3.7L V6 S550 Mustang and add a throaty muscular exhaust note at the same time by installing a MAC Performance Catback Exhaust System. By reducing back pressure with a free-flowing exhaust, you will see rear wheel gains in both horse power 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 Catback 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.
