Rattle noise need help determining (g35x)

Hey guys

I'm a new g owner got 195 km still going strong. I have come to realize that at certain moments when my car is on a cold start it can make a weird rattling noise and it sounds like it's coming from underneath the driver seat. This sound only happens when I'm at a full stop when I drive it's gone. When I put it in park off the cold start the rattle goes away for a few seconds and then comes back. While driving for some time when I come to a full stop sometimes the sound comes or it Dosent please help a new g owner out also just to mention this car has an after market exhaust and I was thinking maybe it's the heat shield

Typically this rattle comes from the catalytic converter heat shields. Give yours a poke and you might see what we mean.

if i were to fix it would it be the same procedure as clamping the loose heat shield like on the exhaust or would it be different for the catalic converter

Some people just get massive hose clamps and clamp her down, up to you.

I ripped mine off. Never had an issue, just don't park over a big pile of dry leaves.
