Went on easy. 3 hours sounds good. Don't know about milage yet. Looks good.

Weak sounding but decent looking on new Ecoboost F150

I installed the Force II dual exhaust kit on my 2012 Ecoboost and I was quite dissappointed in the sound. I realize it's only a V6, but it was very quiet. I think they could have provided larger exhaust tips as well. What i did was take the Delta Flow muffler they provided (3" center in, dual 2.5" out) and replaced it with an original 40 series Flowmaster 3" in/ 2.5" out. Sounds better, but still not overly pleased. Maybe I'm just picky, lol

Installed on my 2012 F-150 XLT EcoBoost V6 Twinturbo. Also with a K&N filter The Throttle Response is unbeleaveable!!! I've noticed a hugegain. the force II is the quietest system For the V6 looks GREAT and rumbles @ throttle and take off but after third gear it's not loud at all This kit you'll wan't to weld the connections behind the Muffler due to there lapped backwards instead of over they Go inside was'nt a prob tho Also they use the stock hangers and it made pipes way to Tight so I had to buy a universal flex connector I think It should come with one on the 3" front pipe up front I LOVE IT AND YOU WILL ALSO !!!!!!!!!!
