I'm in the same boat. The local shop here wants to use a magna flow tru-x muffler DI/DO making a true dual setup. I don't think its that popular on the forum. My main concern is yours: I want a deep tone but minimal in cab drone. I am really leaning towards the magna flow #16869, which replaces the factory with a 22" magna flow SI/DO and all of the piping after including new 5" tips which look really good. It also gets rid of the factory resonators but I think the new tips have them built in. Good luck, hopefully we can both get some help.
