Attention: TDR Forum Junkies 
Am I the only one who finds it really annoying when you hear someone with a straight exhaust system on their truck? Does anyone think that the horrible droning noise being produced by their truck sounds good? A six cylinder Cummins emits the same drone sound as a six cylinder gasser (if you have a straight pipe).
It's amazing how you can kill the droning six cylinder sound and make a Cummins sound more like a V-8 with a simple flow through open chamber style muffler. Every time I hear someone with a straight pipe it always seems to be the type of people who like to rev their engine for all to hear. I just want to stop and try to talk some sense into some of these people. It embarrasses me when I see one of my fellow Cummins owners running around driving a truck that sounds like a wet vac on steroids.
When I installed my Warp Speed Performance exhaust a few years back I actually installed my muffler backwards. WSP said it would extend the life of the muffler since any moisture would pass through the muffler and not be trapped in the muffler core. WSP said you could reverse the muffler on the Dodge or Ford but not the GM trucks because it would be too loud.
The reversed muffler probably increased the dB output on my truck but it's still reasonable. At idle my truck doesn't sound much louder than stock but it does sound much more throaty. I think you can do stacks without mufflers just fine. The stacks seem to do a good job of killing the annoying drone.
