Just bought a 2011 Yukon XL, have an exhaust question

[96lt4c4]

This is my wifes ride, used to have an 07 Tahoe, then a 13 Ford Escape, now a 11 Yukon XL. The Yukon has a Flowmaster dual exhause cat back on it. Not real crazy about the way it sounds in 4 CYL mode. Was thinking about going back completely stock. Or maybe just the stock tail pipe with the resenator in it and some aftermarket muffler, like a Magnaflow. Just looking for some input. Thanks

Do you like the way it sounds in V8? If so, why not disable AFM? Might save you a lifter failure down the line too..

I hqve HP Tuners, and do some tuning work on the side. I can turn it off that way.
I am not crazy abour the duals. The drivers side tends to rattle. Its a little too loud for my wife.
