Nifty little addition  2 years ago
Roadie88
Nice little part and do like. As others have said in order to get the sound at lower daily driving boost levels you need to be at around 50/50 vta when i put it on i was about 75%recirc and not getting the sound. Fyi when putting on first time and reving with head under the hood just to hear it for the first time(every car is different so take with grain of salt) it may sound like a high pitched kazoo but dont let that off put you take it for a drive first before any feelings set in it sounds different when driving and definitely will turn some heads

Very nice 4 years ago

Works very good as long as you are 100% vented. Not much different if you run 50/50.

Great sound!! 4 years ago

Great product. If you are looking for the sound often then I suggest this rather than the high boost trumpet. Currently running Full VTA and you get the sound a little past 3K rpm.

QUESTIONS & ANSWERS

  • Q: Sound   Wrx200512 months ago

    I’m running 20 psi in my 05 wrx, could I still use this low boost trumpet. I currently have the high boost one but don’t wanna run full 100% VTA to heat the whistle sound.

      A:  This is just the pictured trumpet. This will fit on Go Fast Bits Respons Hybrid BOVs and will not fit any stock valves.

      A:  I would recommend the low boost for your application. The high boost is used for cars pushing roughly 26+ psi overall.
