Need Tial Q BOV Advice

[dm874]

I'm looking to buy a new or used Tial Q Bov. I want a loud or pronounced Swoosh sound.
So what PSI spring should I have?
Or does that not matter?

If you want loud, you should go with the HKS SSQV. Although you can definitely hear the Tial, it's the quieter of the bunch.

The spring is based off of what vacuum your car pulls at idle. You shouldn't try to change your spring just to get more noise as long as it's working correctly. Most N54s need the 11psi spring, but many of us have had to go down to the 10psi spring after noticing some flutter.

Tial is very quite.
If you are looking for loud HKS is the best option

My forge diverter valve's make a sweet little chirp sound. I bought them expecting them to be quite but they produce a sound that is intoxicating and I'll never get rid of it.

Does anyone know the price range for the HKS? I see them raninging from $80-150 and I don't want to accidentally buy a knockoff.
Also, can anyone forward me a good video of the HKS sound? i've tried searching for one but nothing so far

HKS sounds very high pitched, most Youtube vids should give you a good idea on how that sounds.

$80 - $150 for HKS? If that's brand new i'd definitely say it's fake....even at used prices that is ridiculous. I just checked my wholesale pricing and it's definitely going to cost you over $200 for a legit one.
