Also if I buy the muffler offline what am I looking for as to 2into1 or what's the piping of that muffler?
Drone is basically a bass sound that is constant at a certain rpm inside the cabin. You can always tell a flowmaster muffler by the drone usually between 2-2,500K rpm. Some people HATE this sound, and others absolutely love it. The difference between the mufflers will be their sound. The 40's and super 44's are very similar in design. The super 44's are a bit louder with a more aggressive sound, and the 40's are a bit more low key but still have a great sound. I suggest you look up sound clips on youtube. It's not the best sound quality, but you will be able to hear the difference with the two mufflers.
As far as the muffler and exhaust are concerned, I would run all new piping from the flange on back. The flange is right after your catalytic converters and is a connecting point to the rest of your exhaust. I had my exhaust guy put the muffler as far back as possible so I don't have to worry about it when I go offroad. I went with the left offset in and center out (this matches the stock muffler). Like the others I didn't put a resonator back on. I like the sound better without it. You can always decide later to have one added in.
