2023 6.6L GMC AT4 exhaust

I was about to pull the trigger on the SS AFE exhaust for my truck and then read a few post about horrible drone during acceleration at highway speeds. Can anyone point me to a single outlet exhaust that doesn't drone for this truck? Being on sale for Memorial day is a plus.
Thanks!
