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.

I ordered both collector and crossover gasket. They look awful comfortable where there at. Not much room for a torch. Maybe lower the rear sub frame a bit?
The bolts I mean. I don't like the little 5mm ones for the crossover
