Is there a good performance muffler that's quiet?

In tried the two chamber Flowmaster that was described as OEM replacement....simply too much droning noise inside the cab. Very load muffler with rack off /popping.
I did a 1-800 to Flowmaster and they sent me a 70 series 3 chamber at their cost plus a pick up and return for the 1 week old two chamber off the truck.
Very quiet with no rack off/popping when gearing down hill.

I kept the oem side dump behind the wheel. Tail pipes sticking out the rear don't last long for what I use my trucks for.
