Key Product Specs
  • Give your rear end a make over with Roush's Enhanced Axle Back Exhaust System with Square Tips and Rear Valence! This combo package gives your Mustang a ferocious exhaust note and increased airflow. Roush's Rear Valence adds stunning style and makes your pony one of a kind. The axle back exhaust is designed to be longer lasting than other performance exhaust systems; the open chambered muffler design gets rid of the fiberglass packing. This ensures longevity because there no fiberglass to break down which means you get a longer lasting system! Those exhaust gases will flow right through the wide open tubing, providing you with more horsepower and torque at your disposal. The aggressive exhaust note is sure to turn heads at full throttle, yet produces little drone and no boom at highway speeds.

  • Quality and performance are at the top of Roush's list, they designed the exhaust with top-notch materials so you can be sure it's not going to rust away over time. The pipes and muffler are constructed from heavy duty T409 stainless steel, while the beautiful exhaust tips are made from durable T304 stainless steel. The chrome flashing used for this kit is bonded micro-porously to the stainless steel, giving it superior resistance to cracking and color changes from heat. In addition, it's street legal and comes with a 3 year limited warranty from Roush! Installation is easier than ever because it uses the factory mounting locations and this kit comes with spherical clamps (just like the OEM ones) for that perfect fit.

  • The rear valence included with this package adds an individualistic look and perfectly compliments the gorgeous square exhaust. It's made from high quality Thermal Plastic Olefin by high pressure injection molding, the same process used by Ford! This combo deal is a sure-fire way to save you time and money by purchasing it all together. Free up some horsepower and add some class to your Mustang with this package from Roush and Stangmods!
