The boomba bpv feels very solid and high quality. Installation on the forester XT was pretty straight forward but required me to look at several YouTube videos to make sure how to disconnect hoses from the stock bpv and how much to trim away for one of the hoses. The boom a bpv fits right where the old on sits. With the combo of a aftermarket air intake, I was able to hear the flutter sound from the bpv inside the car. It wasn’t too loud, it’s exactly what I expected.

Solid and nice looking machined piece that unfortunately
will not be seen. smaller than the stock plastic one. it's not the psssshhh sound that hybrid bov produce instead it produces a nice flutter like sound. I may be in a small group of people here but I wish it was louder, don't get me wrong you'll definitely be satisfied with its volume I just like scaring people when it releases. I definitely recommend it as it's a part that even a novice like myself was able to install on my own.

Best upgrade you can do for stock internal engine, you can hear it very well for a recirc type bov. Very high quality part highly recommend

I installed this and have definitely noticed the performance upgrade aspect of it. Boost spools more steadily and faster as well. My assumption is it’s from the bpv holding it more efficiently. When I went to test the stock bpv it was definitely leaking air ( letting air through while uninstalled) how ever the boomba one did not one bit leak while uninstalled. Love the product and I am hoping to soon get the short throw shifter that a person at my local Subaru dealer recommended.

Very nice looking part, great quality and really works nice. Very noticeable increase in performance and sounds great too.

I recently purchased bypass valve for my 2018 WRX from Boomba. I am so happy I did. I watched the install video, I had no problems installing the bypass valve, I definitely can feel the difference, I had a friend who owned several WRX's take my car for test drive and he knew right away my car was performed better than before the install. I'm hooked! Now looking for some more mods

Purchased this for my 2018 wrx I love this bov. Easy install and sounds amazing with my aem air intake

I purchased this for my 2011 Legacy GT and it fit great with a simple mod and sounds amazing!!! It's a very well made , high quality product. I will definitely buy more from Boomba!!!!!!

Last week I ordered the Boomba BPV for my '16 WRX. I OCD about car stuff and watched tons of videos, read tons of reviews, and talked to my tuner before pulling the trigger. I have to say that, at roughly $100 cheaper than any of the competition, it was pretty much a no-brainer anyway. The product shipped fast, installed super easy (I was doing my Charge-Pipe at the same time), sounds great, and even though I installed a number of other things at the same time, I feel like the way my boost happens and holds now is a lot more solid than with the stock unit. Totally happy with this and I'll definitely look to Boomba for other stuff when I'm ready to add more to my car.
