One thing that came to mind. We put in new motor mounts and springs before doing exhaust. Motor mounts, at least, would have put engine higher, so perhaps the front pipe flange at bottom is closer to the underside. And as a result, so is the exhaust pipe.

There is a clamp at bottom of front pipe that connects to the chassis. Maybe in time that could be loosened off to allow the exhaust to hang slightly lower?
