Cai, 2.55 upper pulley, tb, tune this could get you close to 600whp from what I have seen and should not break the bank.

Not much HP in catback if any. headers seem to work well but are expensive.

I am pondering on lower puller instead of upper and longtubes I think but that is going to cost another $1600 or so to go that way.

if you go into the mods forum there are some vendors that are doing great things that could point you in a good direction.
