Key Product Specs
  • Roush's Extreme Cat Back Exhaust system is a bullet proof way to tack on some muscle to your pony while adding an absolutely mind blowing exhaust tone. Even though its louder and more aggressive than your stock setup, it doesn't produce much exhaust drone that you see with many off-road exhaust systems. Roush's high flow system enhances the airflow throughout the pipes, giving you a much needed boost in power, torque and fuel economy.

  • Roush's Extreme Cat Back Exhaust is made from 2.5 inch T304 stainless steel and features beautifully polished 4 inch exhaust tips. Not only is it heavy duty, but it is resistant to corrosion and staining. It's manufactured from a CNC bender which creates smooth mandrel bends, resulting in more airflow. It even comes with OEM clamps that won't damage pipes when tightened and provide a leak-proof seal.
