I can't remember if you already have exhaust done or not, but if not a nice set of longtube headers, x-pipe, and an exhaust will give you a nice jump in HP....along with the CAI and LS6 intake.

 

i dont want to do header because of

a.) cost
b.) pain of instalation
c.) still dont know what i want to do and dont want to have to install headers twice

soooo im just gonna stick to the corsa catback it came with and hope that is enough flow fromt he back to still make a difference..
