new from the I.E.
wassup! new member from southern california, I.E. area. I ride 2004 cbr f4i black and yellow. just started doing work on it i have an undertail, black wind screen, looking for an exhaust any recommendations should i get a slip on or the headers and all. hit me up to go riding![:@]
A slip on is most common but full exhaust will give the most increase in power. Slip ons are also easy to install (usually). M4 exhausts are highly recommended for F4i's (by me and indysuperbikes.com) for what that's worth.
