hey guys im new here this seems like a badass forum. i just got my flow 40's today with u bend delete and resonator delete. i got a k/n COI commin in tommorow that im stickin in this weekend. oh yea btw i got a 03 SS pace car im wonderin what else i can do to get all i can out of it. ive heard of high flow throttle body/ spacer?

 

high flow cat will help. is yours supercharged or n/a? computer reprogram always helps. simple bolts on help too. how much u willin to spend?

 

yeah... the high flow throttle body. some like the powerlog from ZZP.. it replaces just hte front manifold which they claim is the most resistant. you could also get a down pipe with a high flow cat and have 2.5" exhaust ran all the way back. other than that.. you'll ahve to go internal.
