I just installed an Invidia CBE and was thinking of a Z1 Long tube intake. (No cutting like the Stillen and very close dyno numbers for both.) I have the same concerns also. Right now just threw in some K&N stock air filters and will be getting some post MAF silicone tubes. That is until I can afford to do a HCF, CAI and tune. You should be ok with a CAI and muffler delete. I would do the CAI but I just don't want to do anything to decrease the life of the motor.
