Any one use a full GYTR exhaust? Looking at the Yamaha website,The head pipe looks almost identical to the stocker. Is the GYTR head pipe larger and was it worth the $ in terms of performance. Just wanted some input before I spend my money.

The headers make a good difference in power. I never ran the GYTR one, but I have heard good things. You are of course going to get bigger gains from other things, but the header is definately one thing you want to address.
I run the FMF power bomb....been pretty happy with it
