ROUSH's rear silencer for the Mustangs 2.3L Ecoboost and V6 3.7L is a great solution for anyone looking for a significantly more aggressive sound and an overall better look!

Ford's engine selection for 2015-2024 Mustangs offers a variety of powerful, yet affordable and economical options to suit any budget or sensibility. This includes the V6 and I4 engines, which perform well beyond what their cylinder count suggests. However, Ford's factory exhaust doesn't quite provide the aggressive note or sound that Mustang owners crave; This is where ROUSH Performance comes into play!

ROUSH Performance specifically designed this exhaust to fit both the V6 3.7L and I4 2.3L 2015-2024 Mustangs. Made from T-304 stainless steel, this exhaust is corrosion and stain resistant. Mandrel bends help maintain high flow and continually reduce backlog.
This exhaust uses factory mounting points and fits both V6 and I4 Mustangs without the need for modifications or welding. This exhaust system also significantly improves the sound and performance of your Mustang with single-pipe, high-performance mufflers. To complete the exhaust, ROUSH also adds 2 brand new round double wall exhaust tips, chrome plated for superior corrosion resistance and embossed with the ROUSH logo.
All hardware required to install this system is also included.
