I replaced the damaged (don't ask) exhaust system on my RV earlier this year and upgraded it from a 4" to 5". I also installed the Aero 5" muffler as many others have to finish it off;

Check your exhaust pipe over carefully. I found the elbow portion was really thin. Easy to cut the flange off and have a new elbow welded on. Would be shame to have rotten pipe show up after putting on new muffler.

I suggest the Aero muffler as above. I also suggest to take it to a muffler shop, not Cummins, Freightliner, etc. as all they want to do is OEM parts swaps. A real muffler guy won't have any problem getting you fixed up.

Call me "old-school" but I think the OEM muffler used on Alpines is part of the overall experience that makes our coaches so desireable. The sound of an Alpine is truely unique to the brand--you know its an Alpine from a mile away--ok, maybe a half mile. I am sorry, but the sound of the Aero muffler does nothing for me......IMHO

Thanks everyone I just replaced with a Donaldson oem. Like to do my own work. Had it replace in under an hour. Luckily straps where still good there a bit hard to find.

All - Have had exhaust leak for about a year off and on. After the wreck, the shop installed new muffler, with a flexible pipe which is attached to the exhaust system from the engine. This flexible pipe has broken again, (Cummings put a band clamp on it which cured the issue until this trip (what else is new, every trip something breaks), which caused the flexible pipe to again break just pas the band clamp. I don't know that much about the exhaust system for what I need to get as far as parts go, does anyone have a diagram or a parts list. Was the flexible pipe part of the OEM system, since most of all the lower part was replaced when the lady hit us.

IMHO--those "flexible" pipes tend to get pretty brittle once they age and rust in place--had to put a band clamp on mine 2003 about 6-7 years ago [at Camp WRV no less] but have had no problems since. If the minimum amount of flex pipe was used after the accident to reconnect the muffler, its possible its too short and the normal rock of the engine in its mounts is breaking the pipe, once it rusts "in-place"??????????

Does any one happen to know the part # of the Donaldson replacement? Mine blew apart on my way to Yuma & I'm back in CO! I was hoping to have a direct replacement for when I go back down in a few weeks!
Thanks
Troy
