Best BOV

I have a 2002 Wagon and the boost creep is starting to make me crazy. I want a BOV, but I want to have a recirculating one so as not to draw too much attention and to keep the emissions stuff somewhat legit.



So who makes the best Recirc-BOV?
I have seen Greddy, Perrin and this guy

This is my daily driver, so engine mods are probably going to be limited to an AP, K&N drop in filter, Catback, and MAYBE an upgraded TMIC.

I would love to get some real world opinions

#1, the BPV(not BOV) has nothing to do with boost creep...

BPV = Bypass valve or recirc valve

BOV = Blowoff valve, vent to atmosphere

without any mods I highly highly highly doubt you are experiencing boost creep.

if you are experiencing boost creep your wastegate arm is too tight...btw, it is normal for the WRXs boost to fluctuate some & then taper at redline.
