Robert U Posted July 19, 2021 Share Posted July 19, 2021 I had mine replaced a couple years ago. I took it to a diesel shop and they measured it and got a new one from a truck parts place. Total cost was a little over $4oo Bob U 2000 Dip ISC8.3 1 Link to comment Share on other sites More sharing options...
pulsarjab Posted July 24, 2021 Author Share Posted July 24, 2021 Just did the same thing Robert U did. My diesel mechanic ordered a new muffler. He had to replace the hangers and all connectors as they were rusted thin. Note, the old muffler was nothing but a hollow tube. The entire inside was gone. It was past due for replacement. Engine seems to be running cooler. I suspect the exhaust heat was being blown through the radiators. Just never stop learning. Thanks for the replies.
