I searched and couldnt find anything. Its my understanding sp1 exhausts are different than sp2 and this has to do with the swingarm? Im looking to get a pair of slip ons.......well if they are slipons then they should fit 00-06 since its after the swingarm right? Mines an 01 and all I see cheap are SP2 slip ons for sale but some of the descriptions say (will fit 00-06) some quick help/assistance would be appreciated.
