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

Sounds good and easy to install. Definitely need to adjust your gfb to almost fully open atmospheric.

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.

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

Extremely easy to install. Just screw it on. You will need to completely open the valve to truly hear the difference. If the valve is half closed, you will not really hear the difference. It does sound really nice though. AAA+++!!!

After doing numerous test on the trumpet. If recommend you have the bov set to full atmospheric. When hitting boost over 3k rpm, you’ll definitely here the whistle sound. Got it for my Evo X.
