What are your guy's opinion on the best blow off valves. I have a greddy Type RS now, but I have seen some video's of supra's with a different sounding BOV, like a High pitch sound. What BOV's sound this way?

Ya, I guess it would be like a bird's chirp. Is the SSQ, the only one that sounds like this? And what is most peoples preference?

I have the HKS type II blow off valve but I do not like the snap ring flange design from HKS because mine has leaked. For the money, you can't go wrong with the Tial blow off valve. Good design. good price and quality, and they hold shitloads of boost.

GReddy type S has a high pitch sound too. It's probably my favorite sounding BOV but I like the way the Tial one's sound too

Also when you're choosing a BOV consider how much power you have and which BOV will support that much. The Sard High Boost BOV is a great choice for high HP cars instead of two HKS'

Anyone know what the stock recirculation valve sounds like venting to atmosphere? I prefer a simple air swish sound.

Twin tials here and they sound very good to me, but people looking for a high pitch sound will be disappointed.
