This exhaust is great!!!! It goes perfectly with my 07 Gixxer 750. The sound is awesome!!! I went from the horrible stock exhaust to this beautiful Two Bros. exhaust and lost about 10 lbs and got an increase in HorsePower which is felt as soon as the throttle is twisted. I cant speak on the installation because i took it to my dealership to install it. This is easily one of the meanest, loudest exhausts I've ever heard....It's a major head turner!!! I am beyond satisfied with this Two Brothers exhaust.
I definitley recommend this exhaust who wants a deep, mean and loud sounding exhaust!!!!
