I have the mbrp cool duals, and it was VERY simple to install. Take a sawzall to your old exhaust and get it out of the way, and then bolt up the new stuff. Took less then one hour for total exhuast install on my truck. Use the band clamps no matter whos you go with, its makes life easier if you ever need to move/adjust things, or take it off to do some other mod. Im not a muffler guy, but with the duals you have to run the muffler, and it sounds excellent, very deep sound, and its def. not too loud, but you can still here it for sure. Good Luck!!!!
