Many many thanks to this thread, the OP and the above poster.
I installed VRSF v2 and they rattled when car was idling in drive. The pipes were touching the subframe and the bolt on the otherside. I bought 3 clamp hoses just to be safe, and from 15 mins of test drive, there is no more rattling. I would put a 4th clamp hose in there if I had more time and patience. Overall, I am very happy.
