yeah i wouldent spend the money for it either, but who ever told u not to get a header was wrong, it IS the best up grade u can do for cheap trust me i had a team infinity .18 and it was totaly different with a header it really makes a difference, the stock one is just designed to be restricted, trust me get a header any header that is made out of round pipe is going to be less restrictive than the stock one, and u cant round out the stock one much cuz its square.
