The panels are looking great. I was curious to see where you were going with that skeleton. Some bead rolling to match the tank could be interesting.

From putting a few miles on mine now I find what really woke this motor up is losing nearly 100lbs off the bike. I really like a low end motor too - I don't like having to rev the nuts off it just to move with traffic.

I wouldn't call it fast, but it's powerful and deceptively quick just up to illegal speeds. :)

Finished the muffler. The can is a Two Brothers pipe that I shortened to fit under the seat. The tip was fabricated from 2 Mercedes exhaust tips a short piece of tubing and a couple of jigsaw pieces to close it all in.  I cut the tip off the muffler and made a mount that bolts it all together. Getting it all to line up was a bitch but worked out great. I am going to make a heat guard between the seat and muffler. Next is the exhaust system itself. I already know how I'm going to route it  just need to find some time to make it.

I'm just not sold on the muffler tips. The tail section looks great, but the split tailpipes makes it look cheap compared to the craftsmanship of the pipe and panels.

Maybe a single more subtle muffler would fit the bill. Or rectangular to mirror the subframe under the seat could be cool.

I agree, there is just something that throws my eyes...

That subframe is gorgeous, especially with the panels you made.  I think a couple tips that fill the space cutout for the exhaust tighter and more streamlined is the way to go... like a square box but contoured to flow with the curve of the tail.

As always I'm probably doing a terrible job putting this in words, I wish I had my drawing tablet to show you what I mean a little better.  That being said I love the direction you are going, keep it up, it's a great looking build

I really like the dual exhaust outlets, but maybe there is a lack of visual flow that makes you do a double take to figure out if something is askew.  Seems odd since your fitment is so nicely done - a whole lot of work to get it to this point.  It is hard to tell from the pics, but perhaps the outlet tubes need to be more perpendicular in the vertical plane to the "surface" of the bodywork.  They look like they point down compared to the visual surface they "exit" from.  If you are keeping the factory baloney cut on the tips, it may be impossible to aim the tube right without having the skewed end looking wrong.  Also, with the outlets splayed apart at such a large angle the "Y" is super obvious being so close to the exterior of the tail.  This would not be a problem if you either fit a tail light between the outlets, or add/rework your tail framing to wrap around the back of the outlets like the front does.  If you look at how car exhausts look these days (they are often similar to your scheme with the tips "fitted" into the bodywork), they are usually parallel to the ground, and usually pointing straight back.  I don't think they necessarily have to point dead astern, but when relating them so heavily to the bodywork, they would seem to need to align with either a prominent body line (like the pitch of your rear sub frame) or the level ground to not look awkward.  None the less a lot of great work here - keep it going!

From what I remember about two bros, that is going to be loud. I prefer the 920 engine with a bit of muffling as when it's too open, you lose all of its very limited musical quality and it try's too hard to imitate a Harley without the lumpy character.

I also think you have a great opportunity to show off some craftsmanship with the exhaust and by using car tips it could look rushed and less refined. A nice stainless oval that follows the radius of the cutout area for the exhaust but doesn't drop too far down could be good.

If I were doing it I would come out of the can with a flange with two pipes so it doesn't look like you're making a y as well.

All that said - build it however the hell you want to.
