muffler question

[RTFoster]

I recently took the muffler and tailpipe section off my 06 quad cab dually and put a 2 ft chrome stack with a turn down end and a reducer to hook up to the factory. I am looking for just a muffler with hangers that will go right in to the factory rubbers. I am not going to put the tail pipe section back on for a couple of reasons 1 the soot gets all over the fender, 2 I think it looks better without, 3 more money. I like the way it sounds without the muffler bad a** but might be a little to loud. Does anyone have any suggestions as to which muffler. Thanks
