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.
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
Not sure what went wrong here. I installed this on my Elantra N with the GFB Deceptor Pro II adjustable BOV. This trumpet is so long that it's a struggle to actually install, since it will be pressed against the fan shroud. Also, there is no whistling sound at all. If possible I'd attach a video to show you guys how it sounds. It's definitely loud, but it just makes a "Pshh" noise, not the loud high pitched whistle that you see in YouTube videos of this product. Not sure if mine is just defective or what, but that's the situation for me. (Yes, I tried it with the BOV set to 100% vent).
twist the charge pipe, it will clear without issue.
You have to set it to BOV, I am more than sure from your describtion its set to recirc.
Idk for $40 its worth it i guess its louder
