HKS blow off valve
i actually installed the downpipe awhile back and when it was installed and i would drive it would make like sort of a griding noise really bad. what could that be? or do i need to buy a new o2 housing?
HKS seems a little over rated nowadays...but it looks like everyone in the magazines runs their stuff so people eat it up. search the ssqv, not a lot of good feedback. keep a close eye on your intake tube also, the "suction kit" like to let plenty of dirt by the filter...switching parts on a friends car and throwng that stuff away LOL!
exhaust noise just sounds like the D/P hitting the crossmember, check your clearances and tighten it down evenly.
