Thanks for the information. I'll try it for a while and see how it goes. Thanks again.

I put the American Thunder system on my truck yesterday and I LOVE the sound. Interior drone is a bit noticeable if the radio is off, but in my truck that's almost never. I can't imagine the Force II having any drone in the cab. Then again, I'm running a 3.5 EB.

I'll give it a little time and see how it goes. I thought it should be really quieter also, but it definitely isn't. I guess it's all about interpretation of the noise. I do appreciate the input. I'll give it some time.

Trail hopper, thanks for the information about the system "break in." The exhaust tone is definitely more mellow than the day I picked it up. I thought maybe I was just getting used to it, but the Mrs. had not been in the truck since I first had it installed and she said it was quieter. it's been 16 days and about 250 miles, so if it becomes a tad quieter then I'm really satisfied.

I am glad you gave it a bit of time on the truck, hope it works out for you longer term!

I've been kicking around this exhaust for my '15 5.0. I've had a lot of exhausts and over the loud stuff. I don't care so much about power gains or false MPG claims... I just want something with a nice deep tone that doesn't have cab drone that improves throttle response.

To the Flowmaster guys, or anyone that has a Force II, did you notice any improved throttle response with the Force II setup?

For the money, I'll leave the stock set up on my 2.7.....not much of a difference...does have a nice chrome tip though....hate that ugly tailpipe.....

I didn't notice any power change, but I am up a half mile per gallon on fuel mileage. I like the low rumble around town, but it is still louder than I'd like on the interstate at 70-75.

Has anyone used the factory resonator with the Flowmaster Force II setup? I like the sound of the system now, but sometimes I still get a little too much drone inside. I was thinking about installing the factory resonator, but I thought I would check to see if anyone else has used it with the 70 series first. Any help is appreciated.
