Boost Recirculation valves?
#3
I DO! So do they really make that noise? My GTT used to do it real loud and I loved it..
Ive also heard that they help the turbos spool faster and possibly hold boost better?

Boost Recirculation valves would not make the "woosh". They are just a more durable replacement for the factory plastic ones. If you want some that do make that noise than contact your friends in SP Performance as they used to do a kit a few years back utilizing the HKS Blow-off valve.
