Gives your F150 an Awesome Sound and a Revised Look

The 2011-2014 F150s and 2010-2014 Raptors may be some of the most aggressive and capable trucks on the road, but you wouldn't know it from the way their stock exhaust systems sounds. That's why Roush Performance developed this aggressive F150 cat-back kit. Roush's Cat-Back is a complete cat-back replacement that deletes your F150's resonator and comes with a revised muffler that gives your F150 an aggressive and vicious sound that is bound to turn a few heads that's backed by legendary Roush fitment and quality. The kit's twin-rear exit tips also change up the look of your F150's rear end, giving your aggressive truck both a sound and styling upgrade.

3" Diameter, 409 Stainless Steel Tubing with 304 Stainless Steel Tips

Roush carefully designed and tuned their F150 cat-back kit to deliver excellent sound with Roush quality that you can count on. Each Roush F150 cat-back kit is built around 3" diameter, mandrel-bent tubing that allows for smooth exhaust flow with minimal restrictions. The muffler was carefully designed to give your F150 a deeper and more menacing sound without creating excessive amounts of drone during cruising. The muffler and tubing are made out 409 stainless steel that can resist corrosion in most climates and applications. The twin tip is made out 304 stainless steel and comes standard with a polished finish and embossed "ROUSH" lettering. The cat-back installs right in place of your F150's stock cat-back kit, though will require some trimming for some wheelbase options.
