Doing a little "fore-shopping," I've come to the inevitable aftermarket BOV. I've decided on one of 2: the HKS Super Sequential or the Greddy Type-S. I've heard that he HKS sounds magnificent, but most people opt for the Greddy. Why is this? I've not seen many with the HKS, but it leads my decision, and I would like opinions. Thanks.
