Unique sound! Great customer service!
The seller reached out immediately to let me know the product is black, not silver as pictured. Black was actually my preferred color so that worked out perfectly. The product has a cool unique sound that sets it apart from the standard "whoosh" I call it "lightsaber" noises. Still needs at least 10psi (~90% vented to atmosphere). Easy install on my Respons bpv. 05 Outback XT 18G w/ Verticooler.

Really loud whistle
It certainly whistles! I actually grew to dislike it because of how aggressive the whistle is. It sounds like a falcon in my engine bay. That's no fault of the product tho, it's still fantastic quality

slight improvement to oem trumpet
Installed and took the car out, 0 chirping. But on the plus side it has a nicer sound than the trumpet it came with. install is simple if you can get to the trumpet. For my kia forte gt i took off the air box to easily gain access. much faster than taking bottom plate off. If i get it to chirp I will update but even in sport mode where the bov sound is louder, i got an almost chirp at 5k rpm.. but nothing like the videos. Especially not the truck video review. 11/16/23 - gave an extra star because after a few weeks i like the sound better than the trumpet that came with the bov.

Doest work well on EvoX
So as the other review for the EvoX.... lol. I also have an evox but mr. I read the review and still ordered, he is correct. It only makes the noise some times, but its the fact that our cars spike with boost real bad with mods. I have to assume (becuse after 100 blow offs) anything past 12 to 14psi or before you wont get the good light saber sound thats heard on youtube videos. Add me on insta if you have an x I will do a good video of the sounds with an EvoX. Dallas4g63t.... I gave it 5 stars because shipping was local and im a ricer and spent 40bucks to 🦚 lol

It definitely whistles!
It’s on a ej25 with an adjustable gfb blow out valve.. it can get pretty loud or I can turn it down to barely hiss. It’s everything I expected
