Ok guys, heres the deal. I just got a Greddy Turbo kit w/out intercooler. I want a semi loud BOV, but I dont want something quite as loud as the HKS one. Any ideas? If I buy a univeral one, is there a certain sized flange I will need to get to make it fit?

Also.

I bought my intercooler piping at JC Whitney (for u people who have done it too) but I dont know what sized core intercooler I will need. 30inches? 20? im not sure. Thanks for the help.
