I run a Donaldson 40" M085171, quite happy with it. Before I added a mega-cab resonator it was fine, a little loud when towing above 2200 rpms, and too loud with the exhaust brake on... But all in all its a great muffler, and it has a very high flow rating.

I like the aero turbine. very nice, sounds like a mix of a throaty chevy gas motor + the diesel soundmy donaldson 30" is passable. I have an extra 20" from my setup if someone wants it cheap.

I bought a SS full turbo back system off e-bay. The "muffler" is straight through with a few tiny louvers. It's not real loud but then I've not had occasion to tow a real trailer with it yet. The kit did indeed have everything needed. There are two grades of stainless... not a show truck, I chose the less expensive. I was determined to not have THIS system rot off the truck.

Straight through MBRP Resonator and Muffler - not sure of the length of the muffler. Quiet enough but will start to drone at about 2100 RPM. Nice and quiet at 1500 - 1600 RPM.

One thing I wish some place would do is to do a muffler comparison on rigs with and without stacks and do a tow and performance test with the same exhaust and just swap out different mufflers and use a Decimeter in the cab to see which is the quiesest and yet does not compromise performance. I have read many forums and subscribed to several diesel rags and have never seen a muff copmarison.:smart:
