Best or next performance mod to get without adding a lot more sound???
So far I have this:
Tanabe SuperMedallion exhaust
GruppeM CF intake
HKS Circle earthing kit
I want more power but dont want much more sound considering my Tanabe is pretty loud to begin with. What can I do next?
Crawford Plenum?
Random Tech Hi flo's??? do they increase exhaust noise substiantly?

What about the plenum?
How about the UR pulleys?

I would go with the UR Pulleys if you do not want to affect the sound. Another mod would be the Technosquare ECU, but if you anticipate wanting high flow cats or the Plenum then I would do the ECU after those mods.

Random Technology Cats add about 2dB of loudness in the cab. The human ear starts hearing a difference in 3dB changes (if you have good hearing).
Check out this thread for more on the randoms from a customer.

Hey there Coz! glad to see your around.
I bought a JWT ECU for my Z32 from Coz a while back for a great price and easy core exchange... looking forward to getting one for my Z33 (when it's available).

I agree the single cheapest improvement is a UR pulley (crank) (did the whole set for looks).
Ecu tuning is required if you change the air intake and exhaust a lot. All your intake and exhaust mods have to be completed before you do the ECU.
With all the air mods on my car we had to develop new maps to richen the A/F from 14.7 back to 13.s at the higher revs. Will dyno again today.
