I'm planning on turboing my '01 Z24 and I'm gonna get a custom 2.5" exhaust system too. My question is, should i wait till I'm closer to boosting or just get it now? Am i going to lose a lot of power with the 2.5" without the turbo?
i;d wait...
you never know, you might end up wanting 3 inch pipe later for a turbo...
wait till you have a plan and know what you are gonna do before you start droppin cash.
under 12 psi, 2.25". Over 12 psi, 3" downpipe, 3" full exhaust. But like Event said, wait.
I was a retard, and now I'm permanently banned.
