Re: OEM Pipes
do yourself a favor and get cans from an '02 or earlier. the '03 bikes' cans have catalytic converters in them. they weigh considerably more and i don't remove them. too much of a PITA
the '01-02's are definately fine to work with but the earlier ones are honestly the easiest to work on and lightest post mod.
oh, and as mentioned, fitment's interchangable between years AND displacement
