ok, can someone tell me simply put what i'm looking for.. I have an 03 Z which has the non revup engine right?? so for more power i am looking for the motordyne 5/16 plenum spacer, and?-- the MREV 2? which is the lower intake collector.. which will OR will not help me? Is the MREV more suited for the 06 rev up or will it perform for me too.. sorry.. I'm confused... Also,.. will headers, and/ or testpipes add noticeable hp to my in need of hp Z?!!! Sorry I know this sounds newbie!!!

 

Give motordyne a call. They will sell you the proper set-up for your car.

 

Considering Motordyne says in the instructions that come with the MREV2 thats its a waste of money for a non rev-up , I wouldnt get it.
