Really, for performance, best to just cut the stock ones or some regular stainless long tubes. The headersand manifold wont do anything beaides make it run like crap without a tune to match. You can probably buy a tuned dme online, best bet is the turner packages i think they still offer. I may br wrong, but i think shark injectors are only for 328s, and i think those are buyable based on whatever mods you do have on the car, but rather expensive for the minor gains. I had a shark injector on a 328 once, did help alot, not a drag car, bit noticable.
