      Description

      Sporty Muscle Car Sound. Give your Coyote powered S550 Mustang a sporty muscle car tone with only minimal harshness by installing a SLP Loudmouth II axle-back exhaust system from AmericanMuscle. The Loudmouth II not only enhances the sound of your late model Mustang, but it also enhances performance by drastically reducing back pressure for an increase in horsepower and torque.

      Stainless Steel Construction. Manufactured from 2.5" diameter mandrel-bent stainless steel tubing for its excellent flow characteristics, this SLP Loud Mouth II exhaust system features a pair of straight-through performance mufflers that end with highly polished 4" dual wall exhaust tips for intimidating muscle car looks and sound.

      Cut & Clamp Installation. The installation of this Axle-Back Exhaust requires cutting and removing the factory muffler assemblies, and clamping the new muffler assemblies in place. Clamps and instructions are provided.

      Application. This SLP Loudmouth II Axle-Back Exhaust system is specifically designed to fit 2015-2017 GT Mustangs. Cutting of factory exhaust is required for installation.
