Mac axle backs are on
(2014 GT)
Put them on today, and I really want to share my experience more with the changing of the mufflers more than the mufflers themselves.
Just to get it out of the way, yes, these Macs are every bit of deep as everyone says they are. Super low tone, slight drone at 2k RPM, but timid enough that you won't be catching the attention of every police officer for two blocks if you get on it. They are really light and gave an extra bit of working space when installing.
That said, I spent a good hour alone trying to get the mufflers off the hangers. There is little room to maneuver the mufflers to pop them off. Perhaps a hanger tool would have helped, but I jumped online and was doing a search to see if there was a trick to this. I found that you can remove the bracket that the hangers are attached too, making my hour long venture in to a simple 15 mins. Wish I would have known that from the start.
Once the brackets are off, slip the hangers with the bracket off, then place them on the new mufflers. Might need to grease the hangers first. They are tough to push through.
On a last note. Adjust where you want the tailpipes to sit first, THEN secure the flange connecting the axle backs to the H pipe. I have heard you can loosen the H pipe a bit as well, but I found I didn't need to when I took the route of removing the hanger brackets.

or in reference to your other post, insulate the cabin and fill that spare wheel well with foam insulation.
