Works great! really quick throttle response. Never tried it full atmosphere kinda like how quickly it's back to biulding boost! Recommend.

An awesome diverter valve that feels very sturdy and heavy, amazing sound under boost, I love the flutter that it makes and it's not too loud like an actual blow off but loud enough to hear in the car and fall in love with driving, install took 5 minutes; no directions needed. Gets louder and better depending on how much psi is built up in the turbo. The video is @ 7psi

Great quality valve. I have a Cobb intake with the box so my turbo is loud and it exhales loud as well. This didn't change the sound when i shift high, but when i shift at very low RPM it changed the sound a little bit which I didn't expect this thing to do. not a bad thing, I like it. The only issue i had was when i took the old one off and I had to take the stock elbow off, the 2 screws were on there so tight and the screws were so soft I stripped it in one twist. So I had to drill the old screws out and go to the hard ware store to replace them with stainless steel screws. So I also got to upgrade some screws while i was at it. amazing!

My wife's 2011 STI is what the kiddos call stage 2+. There's much more to it, but we've basically just maximized the stock setup. The car has had a stutter I have been unable to tune out with the AP tuning software. I got it to move in the rpm range, but it was still there. Long story short we narrowed it down to the stock by-pass valve. I bought this as a mothers day gift. I liked that it wasn't intended to be a noise maker for teen tuners. Figured for the price why not try. We installed it in about 15min. And spent an hour making 2500-3500rpm runs to fine tune it. The end result is absolutely no stutter, and her car shifts like a dream! Drivability is improved and it makes the power band more usable resulting in a better performing STI. I will buy another one when I buy my WRX beater!
