okay so i just changed my header setup....

old setup=
shortie - hf cat + custom 2.5" flex [all one piece] - 2.5" borla


new setup=
fs race header - stock flex [for now] - 2.5" Borla - no cat

[only gonna use temp cat when comes time for emmisions]


so my question is....

do i need to re-tune my cams??

yeah because you HAD more low end grunt with the shorty and NOW you have the race header which gives you more high end grunt..

so you would have to re-adjust your cams or your cam gears to compensate for the different power band.

anyone else have opinions/experience with this?

Nah, it should be the same.. The flowage of the new setup should be pretty close to the old setup.. It isn't going to make enough difference to retune the cam gears.. I would do it if you went from a stock manifold, and exhaust. You already had an exhaust and it was opened up at the head so it should be just fine..

The header will only add in the top end just from itself.

We were able to squeeze another 10 hp from airforcefocus' car with tuning of the cam gears. He had a similar change (not exact) in mods. I wouldn't count it out. If it was my car, I would get it tuned again.
