I have an '05 GT with an MMR CAI, JBA shorty headers, B&B axle back, and Hurst shifter. I'm wondering what other cheap mods I can do to give it more punch. I want to spend maybe 2-3 grand total. I'm gonna keep it N/A(forced induction is too much $$). Also, what kind of x-pipe should I put on there to go with my headers and B&B?
