I am hoping that someone can help to shed light on this matter. I remember reading in at least one mag that SD changed the pipe on the 01 MX6 and that the new pipe generated about three more hp. Can anyone confirm this? If true, is the 01 pipe compatible on the 99 engine? Appreciate the input. thanks.

well the SLP single pipe says it fits 99-01 models, so i guess that would mean there is no diff. but i would double check.
