    Just wondering if a 16-20 T120 muffler will fit on a 2018 T100. The mounting location seems to be the same on both. I have heard that the T120 mufflers are ~1" longer than the T100 ones, and the part numbers on the manuals are also different for the two models.
    Has anyone tried this?
    Thanks in advance.

    Yes, they will bolt on. The mounting points are the same. The T120 mufflers are slightly longer, so they might stick out a bit more on the back of your T100, but they'll fit and work fine.
