This will turn your GFB BOV or GFB Bypass Valve into a VERY loud BOV!
THIS IS THE LOUDEST BOV YOU CAN FIND WITH THIS HORN. THIS HORN IS BEYOND EXTREMELY LOUD.
Whistling Trumpet
You asked, we delivered. Many times we have been asked for a replacement trumpet that gives a different sound, and here it is.
The ability to change the sound of a blow-off valve is increasingly becoming an important issue with buyers, who want to sound different from everyone else.
If you're running a 24 Elantra N this won't fit.. that's the only reason it gets 3stars.
Hi there!
Thank you for your review. We apologize that our BOV horn did not fit your 24 Elantra N. We want to make sure you have the best experience possible with our product. All you need to do is loosen the charge pipe and twist it slightly, then it should fit without any issues. We hope this helps and please don't hesitate to reach out if you have any further questions or concerns.
Best regards!
Installed my blow off valve yesterday the install was very tight with the added whistle, but when I went to go drive it, I heard no whistle and was very disappointed. When I installed it, I had looked on the blow off valve side to make sure that the hole was completely open on that side and then installed it to make sure that I did not put it on wrong knowing that there’s not a lot of room to work with once it’s in. Gonna try and work with it a little I read one of the comments before that said the twist the charge pipe, but I don’t know if that’s just for install or if that’s for whistle too 🤷♂️. Other than it not whistling, the sound is amazing and I have no other complaints.
Definitely louder without a doubt
Excelente súper fácil la instalación y el sonido perfecto
This isn’t as loud as some people claim, definitely louder than the T9010 BOV trumpet that it comes with, it’s a nice crisp whistle sound and once I installed it I was more than happy with the result! I suggest taking the BOV off the housing first, unless you have small hands to reach around and screw it in, because the newer trumpet is a bit longer and sits against the front plastics
