Wastegate noise at idle?

Should you be able to hear just a tiny bit of exhaust noise from an external wastegate with a dump pipe at idle?

Or does this mean there's a leak?

I'd say there's a leak. I had to use a copper gasket to seal one of my wastegate V-Bands.

I'd say leak too.
I've had some wastegates go back on and I forgot the fire-ring flange that seals between the manifold and the gate.

Definitely a leak. If too much air is getting past the valve, your entire setup will work harder to build enough boost.
