2racer, Your profile doesn't say where you are, so I am going to post a link to Texas cummins for your muffler:

Cummins Southern Plains Locations

These people will have the correct factory muffler for your engine.

Good luck - Glenn

2racer,
'I needed a muffler('99 ISC350) last summer and took my coach to CumminsCoach Care in Harrisburg, PA. They told me my muffler was not a stock item and had it overnighted from WRV. Total cost was around $420.

Thanks for info, I'll give the local Cummins a call. We are in Pensacola, Fl. but generally have most service done in Mobile, Al. Cummins. Also filled in profile info, didn't realize I hadn't done that.

Thanks again for info, called Cummins in Mobile, Al and they found one for me in Utah and had it dropped shipped to my house, while I was traveling and it arrived a day before me. The muffler was around $114.00 and took about 1/2 hour to install.

2racer,
Can you provide a part number for the Muffler?
I'd bet good money it was manufactured by Arvin or Nelson and the P/N could help a lot of us to cross-reference the OEM P/N.

What was wrong with your old muffler that you needed a new one?

2racer · 07-31-2007, 04:09 PM

You would be correct, the muffler is a Nelson type 5 oval. Part # 86542M. The old muffler's exit tip where chrome extension mounts rusted/broke off and insides were pretty much gone, probably from the wonderful Louisiana roads I travel so often. I had already replaced the flex pc before muffler which I obtained from local NAPA which carries big truck parts.

Just in case your are really, really curious as to how I knew it would be either Arvin or Nelson; in a past life I used to be Director of Engineering for Nelson. Consequently, I am quite familiar with their products (mufflers, silencers and filters). That was long before Cummins/Fleetguard bought them.

During my time, Nelson had 12 manufacturing plants in Wisconsin and I had opportunities to visit or do work at all. At Corporate HQ, where my office was, Nelson had BIG Anechoic chambers they would drive Buses and Tractor-Trailers into so they could evaluate the volume and resonance of engines running at various speeds and loads.
BTW, they were also the muffler supplier to Harley-Davidson, John Deere, Massey-Ferguson, Caterpillar, Ford, International, White Motors, Navistar, etc. Arvin was their biggest competitor but their real money was made by making mufflers for cars.
