Replace your 2015-17 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.

Ordered the cold air and tuner combo. Best tune I have had. Really woke up my 5.0
