Noticed immediate acceleration increase which is what I was after. I have not checked the mpg yet. The sound was exacty what I was after not too loud but has a nice tone. Had it installed professionally and they said it was a little tricky to put on but not too bad. All in all I love it!

Sounds GREAT! Install took modification, not so great.

My wife bought this as a Christmas gift. She ordered the correct type for the make and model of my Tundra. I took it to have it professionally installed, as I don't have the proper equipment to install myself. I'm so glad I did! The system came with NO gaskets and the clamps didn't fit! Also, the hanger on the left side had to be cut and welded to fit correctly. What should have taken 1 hour to install ended up taking 3.

Very easy to install. It took me about an hour. It is not quite as loud as I wanted, but that's ok. The truck seems to have more power. 5.7 liter.

Great Product

I've had it for 2 weeks now and happy with the Flowmaster exhaust.It's got a nice throaty sound and loud when you get on it, but not very loud, nice growl just what I was looking for.I spent alot of time researching and glad that I made the right chose.

Looks great when installed. Installation was very simple, the only issue I had was with the included band clamps. I sheared the bolt on one clamp and was unable to get it to hold. I believe the problem was some type of grease that made the clamp not hold, some rubbing alcohol on the joints probably would have solved that issue. Overall the exhaust has a great mellow sound and drastically improved my Tundras performance.

Was looking for sound without waking the neighbors

I went with the Force 2 over American Thunder. I wanted sound and performance Improvement, without waking my kids up in the morning. I'm extremely happy with my purchase. Immediate Improvement in performance and I'm already up .5 MPG. I'm sure I could get better but I can't resist flooring it to hear that sweet sound!

Easy install. I would make sure to have a good impact gun, if battery powered ensure you have more than one charged. I have a Unichip, CAI, and now duel exhaust. Sounds great, especially when you get on it.

Totally Satisfied with exhaust system

I am very satisfied with the exhaust system. I had it installed at a muffler shop. They had the job completed with no problems in about a 1 hour. The system sounds great and looks good. And no drone, very happy with that.

the sound I desired. Nice subtle burble at idle but not overbearing under acceleration. Cabin sound is the same as with stock system.

Love it!!!
