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?
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.
