Is this noise normal? Coming from headers.

I'm getting a noise from the headers. It sounds like an exhaust leak - but I don't know. What could it be?? I got a new universal muffler, could that be it?

The car is however running fine.

Air injection holes plugged?

Exhaust leak. New manifold-to-head gaskets? Are the header flanges parallel to the head? Any bolts missing? Or a cracked header.....

def an exhaust leak regardless

Ok.. Thats what I thought. I think it started happening after I did the motor mounts and oil pan replacement. Maybe I lifted the engine too much from the crane and bent the headers out of place or something.

What do you expect... You fix one thing and another thing goes wrong.
