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!
I installed this on my 2005 Toyota Tundra because I wanted to free up a few extra ponies. So far I haven't really noticed a difference in acceleration or MPG. The exhaust kit was easy to install and it looks sharp. But I have to give it 3 stars due to the mind numbing drone it has at certain RPMs. I don't accelerate hard at all but it is still very difficult to get used to the increased cabin noise from this exhaust system. If you are looking for a loud exhaust then this one's for you!
