Perrin 3 port boost control solenoid
 

Does anyone know if this solenoid is as good as the prodrive one? And will it fit my STi Spec C MY03.

Just ordered a uprated fuel pump and a forge actuator and am phoning RCM tomoz to speak to them about their exhaust system for the C, does anyone have the non resonated system fitted to a Spec C? How loud is it? too loud for daily use?

Does the same as the prodrive model but is 3x as large. Cheaper though.
Cheapest and most compact is the GM version - it costs about $30 if you can source and wait for it from the US.
