So this is the exhaust im working with :)

i dont ride it because of how loud it is and i dont want to upset people, but id love to ride it more when i get a decent working muffler, I dont have heaps of budget but i got 50 bucks :) Thanks.

It’s the end of a top rail for chain link fence, the reduced end slides over the stinger and is a tight fit, I have a set screw and mounting bracket on it too. If you make a silencer add a mounting bracket to it because the added weight will break the factory bracket. Here’s another, I used what I had in the shop on this one.

The first one was simple, I welded a washer the diameter of the pipe to the big end of the top rail then used a section of the pipe out of a stock muffler as the stinger. I then drilled a hole in the side of the small end and welded a nut on so I can run a bolt through it as a set screw. I welded a bracket on the silencer that bolts to the clutch cover mounting screws. I used a longer clutch cover bolt and added a lock nut on the back. The length of the pipe is a matter of choice, I made mine just long enough to get the exhaust and noise behind me.

That’s the second design rear mount, the first didn’t fit the seat tube like I wanted, the one on it now wraps around the tube and is double clamped.
