ok any1 knows the difference between the GOLD and Purple inserts and which one would be good to have for a better sound..i just hate that HKS annoying bird chirping noise..so will one of these inserts help ..with better sound?

You can always just remove the insert. No chirping noise!

 

[Boosting89]

are you serious? what kind of noise will it make..

HKS USA says right on their site what the difference is. It would have taken less time to look it up there than type up a thread here.


Gold is for visual effect. No change to the stock sound.

Purple is a lower frequency sound.

If you take out the insert completely, you will just have a rush of air sound. A VERY quiet sound. It makes almost no noise at all in the three cars I've been in with it like that.

I have no idea what this chirping noise is. I never touched any inserts and my car is fairly loud. I have heard both lower and higher pitches on cars with my same BOV. It also depends how you shift. When I shift slow you get the smooth slow release and a fast agressive shift you get the quick PSSH really loud which I must assume is what you guys consider the bird chirp?

But then again when my father 30+ years of burning clutches, drives my supra it sounds like someone firing a Shotgun next to my head. No idea how the fuck he drives agressive enough to do that...

It also matters how much air your turbo is pushing. a stock ct and a t04r are going to change the sound of the BOV ALLOT!
