I assume you know that with your setup, you will have no true need for a BOV. But if you're just after the sound, then I recommend the HKS SSQV (which I have) or the TurboXS RFL. My friend also has had successful luck with both the Forge and Worx BOVs. Here's the extent of the damage to my BOV b/c of the hood thing. It can be avoided if you pound that area flat. I can't see any harmful effect if you do.. unless you miss with the hammer or something.
