The ARK also has no hiss with stock cats either. I'm trying to decide whether it's worth it to switch from my RTP to a resonated hfc or if I should just go back to stock cats. They're so restrictive though. The hfc itself will lessen the hiss but I don't know if adding a resonator to the pipe will eliminate it. Im doubting it. The HFC guys have hiss and I have it with an RTP.
