This drives me crazy. Passenger side of the Y pipe leaks at the flange that bolts to the manifold. I’m not sure if it has a failed gasket or if it a bulge type connection that not aligned correctly. I’ve tried tightening but I’#ad

I agree with Ken. Take it apart and verify what it looks like.

 

That was very good advice. For future reference, there is no “donut” or gasket in this specific connection. The picture shows the header pipe meeting the manifold after removing the flange.

I loosened both sides (L & R) of the Y pipe and tried prying the leaky pipe towards the leak. Sir enough, the pipe moved just a bit and seated the leak. I tighten the leaky side first. So far, no leak. Fingers crossed.

Thanks very much for all feedback.
