Replace your 2015-2017 Mustang GT’s quiet and restrictive stock exhaust with our free flowing LoudMouth LM-1 system and get a more aggressive sound while also cutting weight. The LM-1 kit utilizes fully mandrel bent stainless steel 2.5-inch tubing with minimal bends, minimizing backpressure. Custom tailored 304 Stainless steel tips are a perfect match to the 2015 Mustang’s rear fascia. LoudMouth kits use the factory mounting points and come with hangers pre-welded for quick and painless installation. The LoudMouth LM-1 kit saves 29 lbs. over the stock Mustang 5.0L V8 exhaust and is 50 state emissions legal.

As a straight through system, there is no sound deadening material or resonators in this kit. Check your local noise ordinance laws for legality.
