Muffler Replacement For Cummins 500 ISM

[2ofusinabus]

I need a new muffler on my 2005 Monaco with a Cummins 500 ISM.

Where can I obtain a new muffler?

Thanks for help.

The muffler on your Monaco coach was chosen and installed by Monaco-- Cummins only involvement was to give the CFM and back pressure specs that the muffler had to meet.

You can either contact Monaco with your VIN or most large mufflers have the manufacturer and part number stamped on them-- should be easy to find.

What size is your exaust pipe? You may want to look at one of the aftermarket brands.
