Many of you have installed R6 exhausts on your FZ6R. Now that you have are you glad you did? Was the power difference worth the expense/trouble you went through? Did you have to add a power commander or juice box to compensate for the leaner running? Is it now louder than you'd like? From what I can see we'd have to use pre 06 pipes to avoid the dual headers going into the catalyst for it to work. What would be your honest review on this mod?
