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.
