ROUSH?s Axle-Back Exhaust for the Ecoboost & V6 Mustangs is a great solution for anyone looking for a much more aggressive tone, and an overall better look! Ford?s engine choices offer a variety of high-performing, yet affordable & economic, options to suite any budget or sensibility. This would include the V6 & I4 engines, which perform well beyond what their cylinder count would imply. However, Ford?s stock exhaust doesn?t quite have the aggressive tone or sound Mustang owners crave; this is where ROUSH Performance comes in! Constructed from T-304 stainless steel, this exhaust is corrosion and stain resistant. Mandrel bends help to maintain high flow and reduce backpressure constantly throughout. 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 single-tip high-flow chambered mufflers. To finish off the exhaust, ROUSH also includes 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.
