2nd gen exhaust/muffler differences

Ive come across a guy where I live that has a 2014 DCSB with an aftermarket muffler who wants to trade for the stock muffler. I have an 07 DCSB. I'm trying to find out what the differences are, if any, between the two exhaust systems and if this is a compatible trade. I don't know his reasoning yet or what kind he has, I wanted to make sure it could happen before going that far. His truck has around 50k on it and mine has 69k.

 

The only difference is going to be the rear hanger angle is different. Need to mod (bend) or reweld
to fit.

 

most people only want to trade back to stock because the exhaust is annoying. It could drone at highway speed, or is just loud. Definitely get some seat time in his truck before agreeing to it, so you can see what its like.
