I decided to reinstall my tailpipe extension from the old exhaust to the new one. I was getting some low speed drone with it being dumped after the muffler and was also getting some exhaust fumes in the cab with the back door open (putting the kiddo in the car seat) so both needed to be resolved. The outlet of the new muffler was in the same place as the old one so the length of the old pipe was perfect. It's just a little quieter and all the drone is gone. Took me about 5 minutes to do because of the clamps.
