I did the same thing, changed headers and side pipes and was fortunate enough to have dynoed before and after. I went with polished stainless headers with 2" primary tubes and built my own side pipes using 2" primaries into a Hooker headers 4 into 1 collector and a Howe Racing muffler, part #H3002. Picked up 59 RWHP and 50 RWTQ with the change.
