Off the shelf replacement mufflers should give you some choice of sound level and they will all be relatively the same size so swapping one for another will be a piece of cake.

You probably have a stock one or two sitting around that you can build the exhaust system around to get you started.

I am moving in this direction, glad to hear ya'll agree. I was investigating sounds of the 2 trucks that I have with the stock setup. The 6.0 Denali vs. 5.3 is significant. The 6.0 definitely has a little burble and the 5.3 does not. A quick look underneath revealed the the 6.0 muffler is different - soooo, since I have a complete 6.0 exhaust system from a Yukon with the dual inlet muffler like I listened to - I'll be scrapping what I did last night. No biggie since I only spent an hour on it. I'll get that system loose this weekend and delete the cats on it again. The muffler is dual in - dual out, but on a Yukon it converges into 1 right after the exit. I wonder what it sounds like separate vs. merged?
