The stock mounts are like springs and allow the muffler to move and the Dave Brown mount
has a rubber stud mount that allows some movement. I have the Central mount screwed on
with a piece of sillicone under it so it's kinda semi-soft. If I could mount it the way I would prefer
it would hang down way too much so it's kind of a compromise but it's working OK for now. Just
don't pull the zip-tie too tight because the muffler needs to move.
