Didn't work with 50/50 setup
15_STI 4 years ago
I purchased one of these direct from GFB here in Australia and put it on my 2015 STI. Unfortunately, it would never whistle with my preferred 50/50 vent setting on the Respons BOV. I've since purchased the low boost version from RallySportDirect which is working perfectly with 50/50 vent. Regardless, it's a decent product, just get the low boost version if you aren't going 100% vent to atmosphere.

pssssssshhhhhhh Whooooo!

Love It! This little thing makes your boring, bus air brake sounding, GFB BOV come alive. Giving it a very distinct, out of the ordinary sound. pssssssshhhh whooooo! Notes: Tested with GFB Respons BOV T9003 Need to set BOV to 100% Atmospheric in order for it to whistle (as stated in a previous review). Originally tried 50/50 and even with full boost approx. 20psi, no whistle... :( After setting to 100%, any boost pressure above approx. 12psi makes your car go wooo wooooooooo LOL.

The original trumpet didn't fit with those lines on the intercooler, glad I bought this at the same time as the bov! Sounds amazing! Thanks RSD!

GFB BOV Trumpet
AFRanger 5 years ago
I like this, I ordered the wrong one though... apparently I needed the low boost one, wrx TD04 running the GFB BOV and high boost trumpet. So I can't return my high boost one because I put it on, so now I am probably going to get the low boost one and see if I can hear it better with out having to shift a 5K to hear it whistle.... which by the by when it does whistle it sounds awesome. A lot of people are saying they can't get it to whistle, well you have to go 100% VTA to get it to whistle. Just FYI.

  • Q: GFB TMS hybrid  CG_sti 4 years ago

    Answer

    if I am running any where from 15-20 PSI on 50/50 would I still here the whistle?


    • A: Yes, you would definitely still hear it. Any pressure above 12PSI will work with this attachment.

  • Q: Trumpet high boost.   chrisorchard2126689 4 years ago

    Answer

    What does the trumpet sound like at low boost, and I am stage 2 around 16psi will I want the high or low boost trumpet.


    • A: At low boost this trumpet will not have much of an effect on the sound and for 16psi this high boost trumpet is recommended.


      Zach G. 4 years ago
    • A: It makes a normal whoosh sound at low boost, which then changes to the whistle sound once a certain threshold has been crossed. On a T9003 Respons valve, the 5701 will whistle with as little as 12psi, but on T9001 valves you need more like 16psi. This is not because the valves are different, but because of the way the air enters them from the particular intercoolers these valves bolt onto - the T9003 gets a straight shot from the intercooler plenum, where the T9001 goes through a right angle before it goes into the valve.

  • Q: Low or High?  Kappzilla 5 years ago

    Answer

    Running OTS Stage 1 COBB map. 13 WRX I peak at 18psi. Normal driving im around 6-11psi. So I think I need the low boost one. if I get it will it sound weird when I am hitting 18psi? Thanks


    • A: You will want to get the high boost unit. if you get the low boost unit it will not change the sound


      Kirill C. 5 years ago
    • A: I agree the high boost unit will sound better at 18psi, but it depends when you want to hear it whistle... There is a distinct change-over point when the sound swaps from a whoosh to a whistle. If you want to hear a whistle during your daily driving at 6-11psi, get the low boost unit. If you want it only to whistle when you hit high boost, get the high boost unit.
