Hi all. Several archive and google images searches didn't bring an answer. Is the Vanagon 2.1 Ernst muffler basically a straight through design? Or does it have baffles and sets of pipes redirecting exhaust flow? When a cat element fails, do the pieces usually get blown out the tail pipe? On a trip in the Baja, the generic cat (likely Walker) on my Jetta 2.0 started to sound like it had several ball bearings bouncing around inside it. The noise abated fairly quickly but I'm certain the sound was caused by the cat element finally breaking into pieces. I'm wondering if any of those bits could get caught in the muffler or if they just blew out the tail pipe.
