    Nifty little addition  5 years ago

    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

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

    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: Low boost whistle trumpet  Tester3 years ago

      What are the dimensions of the trumpet. Where can I find the dimensions? I want to know the outer diameter.
    • Q: Sound   Wrx20054 years 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.
      • 0 of 1 people found the following answer helpful

        A:  These are recommended for those running 12 PSI, or lower boost levels.
