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.
Not a bad review whatsoever. I will say though, i have a 25 elantra n line and i just got the trumpet. it doesnt make the full on whistle sound like the elantra N even when the BOV is on 100% atmosphere. it makes a tiny bitty whistle noise. it might be because the n line is a 1.6T and not the 2.0T so it’s less boost.
Love it it sounds good
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
