Anyone have a Flowmaster 40 series cat back on a 5.3

Curious who has this setup and how you like it. Mainly curious about drone issues. Let me know your thoughts if you have something like this installed

I have the Super 40 muffler installed in my Dynomax catback......so similar setup to what the Flowmaster Catback would be. I didn't care for the sound of the Dynomax VT muffler, so I swapped in the Super 40.

If you have AFM active still, you'll get the helicopter sound. I have it disabled, so no issue for me. No drone at highway speeds, and sounds really good in my opinion. There is on spot in 5th gear, when getting up to speed that does have a little drone to it...but it goes by quickly and only occurs if you are really lightly accelerating through 5th. Normal acceleration, you don't get it.

Yea after my tire install the v4 barley comes on now it seems so probably won't be an issue until warm weather comes again and then at that I'll probably have my tuner on by then so I don't think it should be a big issue but with music on is that drone really that unbearable each person says the drone is slightly different also I think muffler placement would have something to do with this
