Sounds Great
Review Image by Alan
I got it for a 2011 F150 5.0. It was easy to install and sounds great. I kept the resonator on and it sounds perfect. Its half the price of the Flowmaster Outlaw exhaust and it sounds almost the same.

Awesome sound with or without stock resonator.
Sounds really good, and easy to install. I deleted my resonator as well, gave it a deeper tone and made it crack. To delete the resonator you will need: 2.5" to 2.5" 18" exhaust pipe. Two 2.5" band clamps. Cut the resonator off as close as you can to save stock 2.5" on truck. Don't think it will heat up the diff on the truck like others have mentioned. I put a tip on as well and got it below the diff. I'll do another video later driving. ... show more

It works
It works, but it dumps just infront of the axle. Heating the diff can't be good. Would have perferded it to go put it.
