Replacement muffler?

Years ago, I got local parts house to order two Donaldson mufflers for my 1996 W900 for $175/per IIRC. (REMEMBER, this was years ago, like in 2004). Exact replacement.

Later, 2006 I think, I bought two for my 2004 W900; forgot which brand, (partly owned by Cummins), contacted them, told them what motor, hp, etc, and very helpful lady went so far as to call me with a couple of questions to make sure we were on the same page. After giving me a part #, she also told me that same muffler was used by KW and some Internationals. Compared prices, and guess who was about $70.00 cheaper? Yep, the binder store saved me about $140.00, added bonus, they are seven miles from my home, KW is 52 mi.

I did have to make the brackets for the oval mufflers, as the stock cat style are round.

I would advise you to look under some of the Internationals till you find one that has the muffler you want, get the vin# and call the local dealer for a price check. The company I am leased to had some of those trucks with 500 hp Cummins (single muffler, same part #), Think they recently traded them off though.

Donaldson is considered an aftermarket vendor. To find the best price on their products it is wise to shop all OEM dealers in your locale. The parts houses do far less volume than the dealers. The OEM dealers get better cost and the potential for higher profit. The parts house gets higher cost yet they are willing to make less profit(less overhead, etc). Not all parts houses are authorized Donaldson vendors, these parts house's will buy from the OEM dealers and put minimal markup on said products, profiting even less, yet still charging more than the OEM dealer. My advice for buying "aftermarket parts". Shop around, do you know where all your local OEM dealers are located? Do you know where your local reputable "partshouses" are located? For my customers the logistics are not so difficult. Pete, KW, International, FL/Sterling/WST, Volvo/Mack, Autocar + 3 major partshouses Betts, Fleetpride and HDTraction are all within less than a five mile diameter. Sorry for such a long post but this is just the start.
When shopping around, be honest. Start with your OEM and tell them you need the part number because you are shopping around. This is far more courteous than asking for a discount, or saying something stupid like, "Can I get the part number? So when I come back, I know what to ask for." The partsperson does not buy this. Chances are they will give you the old "bogus part number". Try using that part # elsewhere. There is a general code (amongst parts people) and alot of times the bogus part number will be a commonly used "bogus number"(all OEM's are in on this). This wil make you stickout as a shopper/haggler(and cause laughter amongst parts people). Trust me. Follow my steps for about 6mos maybe less and you will eventually know who to deal with for certain parts(be loyal). It probably will not be just one place. Also consider leaving a "tip"(for your partsperson), not money but maybe a lunch(McDs etc), a sixer, a bottle. I have a customer that gives us office furniture(excess from his moving biz). You do not know what wonders this will work for you. I had a low volume customer give me a sixer 10 years ago that still gets to "jump" to the front of the line and still gets the best possible price. Parts is just a small part of the big picture, yet still a major expense. I have alot of other tips for parts purchasing.
