muffler on 2003 5.3

[white_lexie]

I know this is the yukon and tahoe forum but what is the best muffler for a 5.3 z71 silverado ext cab? I want more power but also a good sound, not looking for something loud but a good tone.

Corsa Touring and whatever Magnaflow's lower end variant is. Same exact tone, just quieter and with zero drone.
