so I looked too and didn't see much
what I did see is that your muffler is clamped on both sides. so buy the muffler of your choice and some clamps. measure the overall length that you need and bring it to a welder/ muffler shop and have them weld it the right length with the flares/slip overs needed and then you can install it in your driveway
I did this once with my old 06 and the old man in the small town general garage charged me 10$ to weld it up. I supplied the pipe the muffler and the measures he thought that was pretty cool
cost me like 35 for the muffler 30 for the pipe and 20 for the clamps 10 for the welds and a case of beer for the install
