There's an exhaust shop my family's been using for 20 years that I will take it to and see what they can do.

 

BEGi S4 manifold? Are you using their brace?

 

yes and yes

 

I don't know the full details, but the previous owner of the car sent the manifold in for repair a couple years ago to BEGi. They fixed it and added the bridges.

The new S4 on their site looks very different than mine. It looks much stronger with the tubes closer at the bend and welded together and then more straight pieces welded in.

 

I got the manifold back yesterday and installed it. It sounds "normal" again.
