They look to be homemade, not pretty........
Those look like turn down exhaust tips for a car or truck. You can find them at most auto stores and on ebay or Amazon. Back in the day I used similar on some of the exhausts I made, but since my bike has chrome I usually used stainless tips. You just need to match the inlet size and length.
Welcome to the forum too. Just a note, this part of the forum is for describing how to do things, not asking questions on them.

IMHO, chopping up the stock exhaust is a waste of time and money.
It does not look or sound very good.
Pulling the stock exhaust completely off the bike and purchasing a decent aftermarket exhaust is the best way to go.

Welcome to the board. I agree, the exhaust tips look like they were designed for the end of a tailpipe on a car or truck.
I've seen worst looking exhausts. Those would look better they were painted to match the type of paint used on the other parts of the exhaust. As far as the rear fender is concerned. I don't see one and I don't see a front fender. Can you imagine riding that beast in the rain?

Freedom Performance Swept makes a 'quiet baffle' but they're hard to get...while I'm waiting I bolted an 'inside pipe JUST inside the tip of the top exhaust pipe that restricts the exhaust a weeee bit. It INCREASED the (3000 to 5000 rpm mid-range power and DECREASED the noise...I know it's a backyard way of doing things but it works...PEACE RIDE SAFE.

That's old school. I put a bolt with a washer welded to the end through the bottom of the pipes on my stock exhaust after a partial gut back in 2008. Nuts inside & out. The washers could be rotated 90 degrees to change the back pressure. Guys have done this forever to (try to) tweak their exhaust.
Iv'e done this for over 40 years , started out doing it on 2-strokes.
When I was a kid I had a Honda 350 Scrambler that had the washer thingy built into the pipes. No mufflers, or I don't remember it having any, just the washer that you could turn to quieten it down in town. It came from the factory that way. The pipes wrapped around the engine and came up high on the left side of the bike.

Two of my friends with the Harley Twin-Cams (Street Bob and a Wide Glide) would bend the flanges on the 'inside' of their THUNDERHEADERS inward to restrict the flow. They said it improved their 'midrange' and would tone down the sound a weeeee bit. The exup valve on the Yamaha Raider will increase and decrease the back pressure. I believe their is a similar valve (can't think of its name) that works the same on the M109...PEACE RIDE SAFE
The 109 calls theirs the SET valve, for Suzuki Exhaust tuning. Same thing as the EXUP valve on the Yamaha.
I don't know if they still sell them or not, but they used to have a thing called "Torque Cones" that accomplished what your friends did to their headers. It was shaped like a short funnel and dropped into the top of the head pipe where it bolts to the cylinder heads.

Maybe he's like me and doesn't ride in the rain. I haven't done that in many years. I have an old beat up 98 Ford Ranger for bad weather, my bikes stay in the garage, nice and clean.
AR cones , anti reversion cones.
Thanks Joe, that was the name I was looking for.

I've following this thread with some interest, and I remember years ago seeing a picture where someone had cut open the original mufflers to show the layout of the standard baffles although after several Internet searches I cannot locate it, anyone remember this at all.
