Rusted exhaust

Got a bit of a surprise yesterday. I changed the oil on my berk and found the tail pipe from the muffler/ def filter to the connection of the tail pipe was rusted completely thru. Has anyone else had this issue? Seems I should not have this issue on a 4 yr old berk. It appears they put heat wrap on the tail pipe section. I think that is the problem.

Maybe it's diffrent for motor homes but I thought emissions stuff is warranteed for 100,000 miles and 5 years or some th ing like that on most cars and trucks.

I agree with your assessment. I think the fiberglass heat wrap does more harm than good. Never liked it on the pipe.

I agree. That heat wrap traps the water and it rusted thru. Everyone check your berk and make sure yours is ok. I went by freightliner they are "checking into it" and will get back to me if it's under warranty. Has anyone replaced there's and kept the heat wrap off? I assume it's on there because of the dpf temps get high.

I got back from a trip last summer to find no more tailpipe. I took this picture to local exhaust shops, and found out that because it was a motorhome and they could not lift it, they would not attempt a repair. I finally found a NAPA jobber who reluctantly got me an elbow, some four inch pipe, insulating wrap, and a clamp. I ordered a polished tip from Amazon, and replaced the outlet in my driveway.

I posted this quite awhile ago. Had the same problem as you. There were lots of comments regarding the regen mode with the new section I put on but have covered more than 12,000 miles with no issues.

Seems like this may be common. I like the side exhaust tip. May have to try that. Did it have any impact on the regen for the dpf?

Yes, you are correct. The warranty is different for a Motorhome compared to a car or truck.

Our motor homes have a 5 yr 100000 mile warranty on emission control. What I have found out is the warranty covers the entire system -- except the last pipe that is rusted out on mine. Apparently freightliner delivers the chassis to Forrest river with out the last tail pipe. Forrest river or any other coach builder puts there own pipe on after the body is on chassis. Go figure.
