The 2WF dude stated that he felt a lot of heat emitting from the CAT. I myself havn't had any heat issues with mine but I still want to remove this filter for better sound and more top end (as if). Anyway, for those of you that have removed it, did the bike seem to run a little cooler from the motor or did you notice "less" heat from the seat? Also, are there any 'How To's" on removing this bastard? Thanks.
