exhaust buzzing noise 2006 dts
I've heard it for a while now I can hear it in the firewall kind of behind the steering column. Also hear air passing on parked cars and such. Problem is I see no carbon. At all, anybody have any similar problems? I've replaced the egr gasket just out of chance. No dice

Exhaust manifold gasket (uncommon) or exhaust collector to cat flex flange - a little more common. MAYBE a loose cat heat shield - tap it with a rubber malet.
