Exhaust hanger.

I mentioned that I didn't like the look of the standard exhaust hanger clamp/band that was supplied with my Supertrapp exhaust. And that I wanted a somewhat tidier looking solution. This is how it turned out.

We welded a little stainless "stud" (is that the word?) with some M8-treads in it onto the back of the exhaust, bolted a new hanger to the stud and then welded a mount for the hanger on the underside of the tube supporting the seat unit. The hanger was laser cut out of 3 mm stainless, which is a little bit too Krauss-Maffei, but there was a little bit of a miscommunication over the material choice between me and the supplier... Since I had planned to powder coat it black anyway, and the hanger isn't very heavy, I chose to keep it. It's too bad you can't make a whole frame out of stainless (It's too brittle) – I just love the feeling of longevity you get with properly manufactured stainless pieces. Pardon the crap mobile phone-image.


  1. have you welded some sort of spreader washer over the bush that's welded to the Megaphone?
    The Supertrapps are nice and thin to keep them light, and they might not survive a bush welded square on. Good luck!

  2. Spreader washer? What does one of those look like? Sounds like a good idea...


  3. the name refers more to the function then to the shape. it can look like anything. the idea is to spread the load over a bigger area.
    in your case I would weld a patch on first, about 60mm dia, then the bush. but you can just as well make a patch with a hole and slide it over the bush. maybe even a little conical, depends on your taste and ability...
    the target is to load the metal sheet of the exhaust tangetial over a big area. Good luck!
