TMS Respons Adjustable BOV by Go Fast Bits | 2015+ Subaru WRX

Dude this thing is sick! makes my car sound like it has an 80 trim turbo lol. the bov sound is so deep in tone and soooooo sooo loud like it reverberates off off walls and cars when i drive by and its even super loud with all the windows up! ive noticed way faster spool time and overall throttle response just feels smoother. im running it like 60(vta)/40(rcirc) and its just crazy loud, only side effect currently is more backfire ;) but im assuming i just need to adjust the preload more to eliminate that (its currently ~3mm screwed in which was the recommended setting from others). i have not noticed any stalling, cutting or fluttering issues and i am currently running the MAP stage 1 tune. But yeah the bov is super worth the money if you want that turbo car sound which like who doesn't?

It’s really good if you don’t mind it running more gas didn’t really get a big noise or noticed Anything to be honest besides running more fuel but other than that it looks cool and fun to install.

amazing product.

Exactly what I was looking for.. definitely will bring a smile to your face. 50/50 setting is super loud, found my happy medium at mostly recirculating. Installation was straightforward and fairly easy.

Came fast and well packaged! Instructions were pretty cool and detailed. This was really easy to install! Does not need any kind of tuning you can make it as loud as you want or as quiet as you want. It's adjustable!! I found that 60% recirc 40% atmospheric works well not too loud not too quiet. You'll have to do some adjusting with the tension on the preload to get it just right. You can do all of this from the top of the car you won't have to go back under it again! Makes it nice and easy! I would def get this because the stock recirc valve is a pice of crap and made of cheap plastic !
