2017 Exhaust Muffler Compatibility; how to discern what fits?

[LSaupe]

Purchased a trike with an aftermarket exhaust, now trying to convert back to OEM. The BRP parts link doesn't help much. I see an OEM number of 707601732, now superseded by 219800442. I also see tons of what folks ID as "F3T" mufflers out there, but many with what appear to be random part numbers without good cross referencing (or even part number recognition) on the BRP parts site. Some have what appears to be a side entry and some an end entry (pics below). Rubber mount and bolts too, etc.

Anyone have a 2017 F3T willing to post an image of your muffler or maybe ID one of the two below (end or side entry)? Do most of these F3T mufflers fit up and have just cosmetic differences, or is there just a bunch of variations through the years which make it year specific?

I am not sure, but that actually looks shorter than what is on my F3L (same for F3T). It looks more like the one that is on the F3S or the standard F3 series. This looks a little short for the F3T. Maybe someone else can chime in. I wish I had the stock F3S muffler on my F3L. I love the sound a lot better.
