2015-2017 Mustang V8 Axle Back Exhaust LoudMouth LM-1 

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.

 Established in 1987, SLP has stood for quality performance enhancements for late-model American Muscle cars from the beginning, and it continues this commitment today. SLP's initial claim to fame says it all: It was the first company in the performance aftermarket to develop and manufacture a 50-state emission-legal performance package -- specifically for V8 Camaros and Firebirds. True to its name ("Street Legal Performance"), the vision of SLP's part program is to not just provide performance, but to do so with the best engineering practices and quality possible, far exceeding the industry standards.

No discounts can be taken on SLP products. The price shown in our lowest price available.
