Hello guys, I know a lot of people don't like the 08 exhaust system, and say it sucks and so on. I can't afford an after market exhaust, but I am getting a really good deal from a friend on the whole 08 system. From what I have read it bolts right in, my question is will I need to rejet? I am coming from 2stroke and really know nothing about 4 strokes, I have just been reading a bit, and was wondering if there is something else I need to know. I am not worried about losing power, as this is too much for me anyhow. I don't race, just cruise, mainly following my son. Thank you for your help.
