The dynomax ultraflow is a straight through muffler as well. No baffles or narrowing, just straight through piping.

What about the off road durability of the mufflers. The Flowmasters look much tougher but that's just pictures.

Well I dont off road much but the little I have done both my flowmaster and dynomax worked fine. Granted I dont think either hit a rock, but I will say flowmaster mufflers rust/rot out pretty fast. Took only one winter to rot my super 44.

Is the drone you are talking about with the resonator still on or with it removed? I just bought a Super 44 OR yesterday because I had been reading about it in the KK section, but if I'm not going to be able to hold a conversation while driving on the highway that is going to make me think twice about this...

There definitely is a drone with the flowmaster, but youll be able to talk while driving.
