I was wondering if anyone has had any experience with a Turbo Tuf exhaust? How is the quality and horsepower after you get it on? The strange thing about the one that I am looking at is that the website says 3 inch, but this one is only 2 and 1/2, I was wondering since the main cat is still there and has a diameter of 2 and 1/2 how much difference would a half inch make with performance?

 

http://www.imp-auto.com/turbotuf.html Is that the address of the site you are looking at? That is the company that makes the turbo tuf systems. I live 3 blocks from that shop, they suck, their prices are outrageous. Honestly I looked at that system up close and it is no better than a greddy aor apex'i system. Also I think it sounds like crap on a 7!!! Just go with an apex'i or greddy system, you won't be disapointed.
