Depends if you are running catless downpipes too.
MT vs AT has a lot to do with it...after the magnaflow, I did a custom catless with only dynomax turbo bullets on my MT, it had some drone, but not that bad and only about a 400 rpm range, when I bought the auto and swapped all my mods, the drone was about 50% worse over about a 1100rpm range...had to add a couple of vibrant resonators to take care of it
