A while back I found a video of an ST with either an aftermarket recirculation valve or a bov. The sound was more of a high pitch cough than the whistle noise i associate with most bov's.

Any ideas as to which of the aftermarket options would provide this noise?

Thanks

Thanks for the help! This peice at first glance looks really nice, and out of my budget. Is the piping kit required to instal this?

the cp-e kit comes with charge pipe with flange welded on, oem diverter valve block off plate, MAPtap (vacuum source adaptor), vacuum line, clamps, couplers, and optional bov valve. Make sure if you buy the kit you buy it with the valve unless you already have the HKS.
