Does anyone have any suggestions for exhaust modifications on my Yamaha? I didn't want anything that would burn a hole in my pocket but I am so sick of the wimpy stock exhaust. I was also wondering if adding a custom exhaust would increase the HP at all or affect the pressure intake on the bike negatively as I do not want to do anything to harm my FZ6R. Additionally would you think that this would diminish resale value or not? Thank you.
