  • Fits 2015-2020 F150 5.0L, 3.5L Ti-VCT, 3.5L Ecoboost (non-Raptor), or 2.7L Ecoboost engines - ALL cab and bed configurations
  • Increased air flow and less back pressure to help reach the truck’s full potential in horsepower and torque
  • Chrome flashed T-304 stainless side-exit tips with ROUSH logo
  • 3.0" diameter muffler & inlet/outlet pipes; Made from high grade mandrel-bent stainless steel
  • Hardware, instructions and 3-year warranty included with purchase


Amazing ROUSH sound is sporty and aggressive. The muffler, inlet, outlet, and y-pipes are made from high-quality stainless steel to prevent corrosion and enhance durability. Exhaust tips are constructed of high-quality stainless steel that have been chrome-flashed for superior corrosion resistance and durability, and are embossed with the ROUSH logo, which exit out of the side of the vehicle. The piping in this system is 3-inch diameter, and mandrel-bent to promote consistent flow throughout. Other companies tend to crimp-bend their exhaust, which can cause restrictions and inconsistent flow. This exhaust kit is designed to work on all cab and bed configurations for the 2015-2020 F150 with 5.0L, 3.5L Ti-VCT, 3.5 Ecoboost, or 2.7 Ecoboost engines

The tone of this exhaust is amazing on my Grandson's 2019 F150. The minute he started the engine and put on some gas could not keep the smile off his face. He and a friend did the install in about 4 hours with supervision of Grandpa so a great experience that he got to do the installation on his own!It also has a great deep tone and not the stupid fart noises of most of the kids cars out there!

What I like the duel tips sticking out behind the rear tire but I just like way too loud from my old ass. Maybe when I was 21 I would’ve been all about it. Also definite drone inside the cab in the lower gears like going down my block per se.

Deletes factory resonator with a straight through muffler design. Pretty loud and drones a bit at some highway speeds. Sounds great though, it gives the 5.0 a great deep tone. Overall happy with this product. Picture shows discoloration I wasn't happy with and seller didn't give any reasonable fixes (outside of returning the whole system) to this problem so I spray painted the insides of the tips black and it looks much better.

Well I do want to start off with, if you drive your truck everyday you may want to: A. Dynamat under the back seats and the back wall, or B. Go for a quieter exhaust.I bought this with the Roush performance pack (Air Intake and Flash for ECU), and figured it would add that iconic Roush mustang sound. I did just that, this will make you truck should extremely loud on the 5.0l models, 45 is about the only speed around 1500rpm ish that it's similar to factory. But if your speed limit is above 65 its going to be loud and sound similar to a souped up Harley motorcycle.Installation was simple, only thing you really need is a tool kit and a lift. Just simply bolts/clamps on, might be a good idea however to clean under your truck so you dont get blinded and covered in dirt if your an off roader. The roush tip may need a bit of tweaking to get that even look but there is enough room to space them closer together or farther out on the tailpipe.
