2015-2017 Mustang GT 5.0L V8 Flowmaster Outlaw 3" Cat-Back Kit 817734

Extremely Loud and Hyper-Aggressive Outlaw Kit from Flowmaster

You can always trust Flowmaster to give your Mustang one of the most aggressive exhaust notes on the planet, but the Outlaw Cat-Back Kit for the 2015-2017 Mustang GTs is something else entirely. The fact that you don't need a background check for this system is a questionable decision on Flowmaster's part. This kit is loud, deep, throaty, and absolutely ferocious thanks to its large exhaust tubing that's mated up to "practically-not-there" Flowmaster Outlaw straight-through mufflers. This kit has a monstrous roar and helps improve your Mustang's performance thanks to its larger diameter tubing and more efficient construction, adding mild power gains with improved fuel economy and lower exhaust gas temperatures. While gains are nice, the Flowmaster Outlaw System for the 2015-2017 Mustang GTs is an out-and-out sound enhancement that will get your brutal 5.0L-powered Pony screaming down the road or the track.

409 Stainless Steel System with 4" Polished Tips

The Flowmaster Outlaw 2015-2017 Mustang GT Cat-Back System bolts on right in place of your factory cat-back kit and doesn't any cutting or welding. Each one of these kits are made up of 3" diameter tubing from the mid-pipe connection to the mufflers that is all mandrel-bent to ensure smooth outflow and minimized back pressure. The kit's mufflers are part of Flowmaster's brutal Outlaw series that are built to generate massive levels of volume and a deep, aggressive roar that puts practically any other kit to absolute shame. The mufflers are capped off by 4" diameter polished stainless steel exhaust tips embossed with the Flowmaster logo that give your Mustang an awesome look. The entire system is made out of 409 stainless steel which can resist corrosion in most climates.

Fitment: 2015-2017 Mustang GT 5.0L V8.
