Been reading about people using a 03/04 636 header on different years; including on a 08 ZX6R. Have any of you guys or girls heard any truth to this? If so, will it bolt right up without any mods? Just looking for a header instead of selling my slip on and purchasing a new full exhaust. I've looked at Pinebox and MJS but this header looks and will work the same as:dunno. I know I've even ready someone on here talking about it but I just want to confirm before I spend some cash. Thanks to all who post.
