Adds deep, throaty sound and nice look

3" diameter, 409 stainless steel system

Requires trimming on some models
Backed by a 3-year limited warranty
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-side 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 of 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.
Fitment:
2011, 2012, 2013, 2014 F150 5.0L
2011, 2012, 2013, 2014 F150 3.5L EcoBoost
2011, 2012, 2013, 2014 F150 6.2L
2010, 2011, 2012, 2013, 2014 SVT Raptor 6.2L
Flange Modifications Required for 6.2L Applications:
F150s with 6.2L V8s will require reusing their factory Y-pipe flanges, which will require cutting it off of their stock resonator/inlet pipe assemblies. Roush includes instructions for the procedure with their kit.

2012 F-150 XLT 3.5L Supercab 6.5' bed
Great quality product and very easy install! The hardest part was getting the old exhaust system out from up and over the axle, and cutting the center piece to length. Had a friend help with the install and it took less than two hours. FWIW: the Supercab + 6.5' bed required ~16" to be cut off the center piece. The exhaust sounds great, a bit louder than I expected (some drone from 2000-2500 rpm), but otherwise it is not very noticeable. Very quiet at freeway speeds!

Fantastic quality and even better sound. Little less than 2 hours to install with a second person. Awesome job Stage 3!!! Only down fall was waiting for it to be delivered because of the Covid. I’ll be buying from you guys in the future!!!

Roush exhaust sounds exactly how it expected to. Mild at start up, loud when i want it to be. Kit was easy to install. This exhaust kit is a one size fits multiple models but Roush marks where you need to cut for it to fit you're truck.
