Love to hear this in person. Do you have any units in the Denver metro area? Specifically, for the 3.5 liter ecoboost.

Most likely we do. You might have to start a thread in one of the Regional Forums to find out which forum members are running this system in the Denver area.

Regional threads. I'll try that. Thanks.

Good luck!

We have confirmed that Flowmaster's Force II Cat-back exhaust system for the 2015+ Ford F-150 (Part #817727) will carry on through the 2017 model year for the same sub-model configurations as previously listed. If you have a question about this system, or any of our other products, don't hesitate to give us a call at (707) 544-4761.

I had the Force II cat back installed today. I wanted a low rumble with minimal interior noise increase. The interior drone is way too much for me. I'm having the factory exhaust put back on tomorrow. I'm really disappointed. I had a Flowmaster 70 series on my Avalanche, traded the Av for the F150, and I only had a slight interior noise level increase.

I guess you live and learn.

What engine do you have? I have this system on my 5.0 and it isn't bad it all...way more tame than most other cat backs. I will say it definitely 'breaks in' after a little use...it mellowed out quite a bit after I put about 500 miles on it. I would highly recommend you keep it on for at least 1 full tank of gas before you take it off.

I had an mbrp system on my last truck...the flowmaster is way more tame.

I have the 5.0 also. Thanks for letting me know about the "break in". The noise inside is just too much for me. I guess I'm getting to old now. Lol.

The interior noise will definitely mellow out after a bit of use. The first day I put it on my truck I thought it was WAY too loud for what I was looking for. It calmed down noticeablely after a little use. I am getting too old for super loud exhausts (on my vehicles) as well. I like a little v8 rumble but am not looking to go obnoxious. This system definitely fits the bill...at least for me anyway.
