Hey I was looking on the search and the question came up but I never seen anyone answer it. Anyway I have a HRC Stage 1 and I was thinking about buying a Greddy Type-S and I wanted to know if I were to order it should I just order the kit for the VR4 or GS-T/GS-X cause I know the BOV that comes with the HRC Stage 1 is a Mitsu. but I dunno what for. Also if I did get the Greddy Type-S on the HRC Stage 1 would it sound and perform well. Thanks in advance
