k, well i found a shorty header. I know they get less gains on these cars. But is the gain that much that i should look for another header (longtube). Like say ZZP shorty vs clearimage longtube. What would be the difference in gains compared to each other. Does anyone have dyno numbers or have either of those setups on their cars?

A shorty header will give you more of a gain in the high rpms. Its really about where you want your powerband to be. And pricing of course.

Well i found this at a great price so i pretty much cant turn it down.

Go for it. I don't think you will be dissapointed.

What you think the gains on the header with catless dp will be?

i think shorties should be left for people planning on doing valvetrain and expanding upwards in the rpms, long tubes have proven to show the best gains, mine definitely felt much better than my CA shorty header ever did. Catless downpipe isn't going to help very much, and is going to be a great deal louder and you'll be wishing you had your cat once its gone

which header did you get?

zackss

if it's the jbp vortex

its a zzp shorty. But im debating. Longtubes are nice. I had em on my probe gt. They felt alot better. I had no cat on that thing and it purred. I loved it.
