ROUSH's rear muffler for the Mustang 2.3L Ecoboost and V6 3.7L is a great solution for anyone looking for a much more aggressive sound and overall better look!

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

ROUSH Performance has specifically designed this exhaust to fit both 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 constantly reduce backpressure.
This exhaust uses factory mounting points and fits both V6 and I4 Mustangs with no modifications or welding required. This exhaust system also significantly improves the sound and performance of your Mustang with single flow high performance mufflers. To finish off the exhaust, ROUSH also adds 2 brand new round double wall exhaust tips that are chrome plated for superior corrosion resistance and embossed with the ROUSH logo.
The scope of delivery also includes all the hardware required to install this system.
