I have an Active GT S650. I installed the Rouch H pipe. The sound perfect in all modes.

BUT.

When in any mode other than quiet, during deceleration, I can hear tinney rattling sound. It's very odd and annoying. Again with valves closed no rattle.
I thought maybe a lose valve but had someone rev and decel while I pressure a long screwdriver against valves. No difference. All clamp tight and secured with no touching anywhere
I have been installing aftermarket and free flow exhaust for 30 years and this is a head scratcher.

Any thoughts.
Thanks

No. Tight as a drum.
