Muffler Replacement - Stock?

[Ironhorse]

Would anyone know what is a currently offered replacement and stock sounding muffler for a '99 Tahoe with 5.7 Vortec and 2WD. What ever muffler is currently on my recently purchased daily driver is the most annoying muffler I have ever had the dis-pleasure to listen to. The drone at any speed is just obnoxious to listen to. It's not loud but the constant drone is just too much.

Not sure what is under it now but next week will find a shop I can get it on a lift to take a look at it. Used to be that a good Walker muffler was a decent replacement for an original stock sound. Don't want a "performance" muffler, just a decent suitable muffler with a smooth quiet sound that is not so annoying at cruise speeds or driving on the streets in town. As mentioned it's a daily driver, and currently the drone from this muffler is very irritating to listen to.
