Roush 2018 Mustang EcoBoost Catback Exhaust Kit

The ROUSH Performance Cat-Back Exhaust Kit for the 2015-2018 I4 2.3L Ecoboost Mustang is a great solution for anyone looking for a race-inspired and aggressive tone.

Fords engine choices for the 2015-2018 Mustangs offer a variety of high-performing, yet affordable & economic, options to suite any budget or sensibility. This includes their 2.3L I4 engine, which performs well beyond what their cylinder count would imply. However, Fords stock exhaust does not quite have the aggressive tone or sound Mustang owners crave; this is where ROUSH Performance excels!

ROUSH Performance has a specially engineered this exhaust for 2015-2018 I4 2.3L Mustangs. Constructed from 304 stainless steel, this durable exhaust system is corrosion and stain resistant. Mandrel bending has been used during manufacturing to ensure high flow and reduced backpressure constantly throughout the system. This exhaust uses factory mounting points and will fit without requiring any modification or welding. This exhaust system also greatly improves the sound and performance of your Mustang with dual single-tip high-flow chambered mufflers and integrated mid-pipes.

To make sure this exhaust looks as good as it sounds, we also include 2 brand new round dual-wall exhaust tips, which are chrome flashed for superior corrosion resistance and are embossed with the ROUSH logo. Included will also be all necessary hardware to install this system.
