What is the deal with Donaldson Mufflers???
I have an 07 CTD and would like to upgrade flow characteristics and reduce EGT's of my existing exhaust system. My stock system is already 4" and I have installed a test tube to replace the catastrophic converter. There are no smog laws where I live. I have been told that the Donaldson muffler is "the only way to go". Is that true? Are there better alternatives. Should I chuck the 4" stock system and go for the 5"?

You don't need a whole new system unless you're over 600 hp or so. Donaldson or Nelson mufflers are a cheap alternative to loud obnoxious aftermarket muffler, my 40" Nelson was $67, pics and part numbers in my gallery.

Is there a Cummins store down there?
If not maybe try one of the big rig shops?
They put mine in with 2-45* bends to make up for the offset of the stock muffler:
