I have fully stock 93 R1.
I am just curious that someone told me that he heard rx7 passed by with BOV sound like double Pish Pish. Not one Pish, two times of Pish Pish at one blow off.
I read some threads about pull the hose from air box to AVB/BOV to have Pish noise. However, will that bypass make the noise to go Pish Pish or just Pish.
Does pish pish noise can be done by bypassing CRV and AVB to the air box?
Once I pull the hose from the air box, do I just leave the hole on the air box or seal it?

I know my question look funny, but I was trying to find the answers on forums and google to bing.
Also, excuse my knowlege about FD,,,,,, I am just a newbie.
