Features:
The Go Fast Bits Response blow-off/bypass valve system for 02-07 WRX and STI is much more than simply a noise maker or a factory valve replacement. The Go Fast Bits Response valve features the GFB Turbo Management System (TMS), designed specifically for the purpose of turbo lag reduction. Go Fast Bits in-house testing facilities have measured a return to peak boost up to 30% faster between shifts than most factory systems, giving you quicker on-off boost response and faster effective acceleration potential.
The Go Fast Bits Response bypass valve features their patented adjustable venting system, allowing you to adjust the sound and vent volume on your valve like a stereo volume control. Vent or recirculate your boost and turn up or down your Response volume as you see fit! The unique Response adjustability allows you to fine tune your turbo system for better drivability while still getting the traditional atmosphere venting noise. Leave those little noise makers behind and upgrade to a system tunable to your Subaru without triggering that dreaded check engine light and compromising daily drivability. This is a direct factory replacement kit that includes everything you need for a complete install with no cutting or further modification to your WRX or STI.

Super quick and easy install. Set to 50/50 for a balance with no tune, no dash lights. Sound is great with stock intake. Can also close and make it a bpv if you don't want sound and vent to atmosphere.
I live with the way this thing looks under the hood. The adjustments between recirculating and atmosphere is so easy definitely a must have for any enthusiast.
Received it within 5 working days which fascinating for me who lives 6000 miles away from USA main land.
The product is solid and sounds amazing
Only when I park my STI with running engine and the BOV adjusted more than 50% open the engine run with a rich condition and I start to smell gas.
The screw is adjusted and now no smell at all
Thanks IIR
Took maybe 30 minutes to install. Sounds great and no issues so far. The adjustability of being able to make it a bov or a bpv made it a no brainer purchase for me.
Have it installed right away after got delivery and love the way sound is no issue for my car and love the fact that I can adjust it
Aussie products are awesome. Didn't have a problem fitting this in. I can have it quiet or loud or somewhere in the middle with the adjuster. The Allan key adjuster on the top makes it easy to figure out where it needs to be so the engine doesn't drown out.
