RMA-01 is very nice.

I'd say Intake, Toda Header, Cat, Fujitsubo is worth about 8-12 hp. A lot depends on where you car is at stock. Tuned you should see another 4-8 hp.

I'd say untuned you are looking at 180-182 and tuned 185-190. THese are VERY ROUGH guesses but are based on the parts you are asking about and seeing all the different R's reaction to them.
