Since you are pulling the motor though you really should do the inlet piping then. If you can't afford both do the inlet with the engine out and add the IC piping later.
I highly recommend you go Ashspec for all the piping and IC's. Call Greg@SZ and he will set you up with a package deal. You will pay less or the same as going with Z1 or CZP and end up with a much nicer product.
