I know there is a post about this somewhere but i couldnt find it. I just got this mac prochamber installed and it seems a little sluggish compared to before off the line. Is this all in my head or does this really happen? I dont have any headers but full cat back flows. Any thoughts?

I remember that thread. I believe it went something like "you lose tq down low but gain it back in the higher rpms." I'm like 95% positive that's what it said.

ok, well I guess that is cool. If I add shorty headers will it give some back, I know that they are more for high end speed as opposed to long tubes, but they are better than my stock manifolds right?
