Description

The Roush Axle-Back Exhaust system delivers an aggressive and raspy sound for your 2015-2017 V6 Mustang, letting everyone know your vehicle has arrived. Its innovative design incorporates hollow, open-chamber mufflers that increase airflow and produce a distinct sound without the in-cabin 'boom' often associated with performance exhausts during cruising speeds. It features two unique open-chamber mufflers and eye-catching 4-inch round stainless steel tips with a polished chrome finish that resists discoloration from exhaust heat. The tubing diameter is 2.50 inches, contributing to its performance characteristics. Installation of this axle-back exhaust requires cutting and removing the stock muffler assemblies, followed by clamping the new Roush muffler assemblies into place. All necessary clamps and instructions are included. The estimated installation time is approximately one hour, with a difficulty level ranging from light to moderate mechanical skill required. This Roush Performance Axle-Back exhaust system is specifically designed to fit 2015, 2016, and 2017 V6 Mustangs, providing both enhanced looks and an aggressive sound profile. Note that it is not compatible with the 2002 models.
