I recently purchaced the MZ Miami expansion chamber like this one.
The thing is crazy annoying loud, so loud I would never drive it in town. I was talking in another thread about a muffler solution. Some have either welded a stock or aftermarket muffler on the end of the MZ pipe.
After looking around I found this little universal Supertrapp type of baffle...

It fits perfectly in to the MZ pipe. I needed to pound it in with some light taps with a hammer and dowel.It fits so nicely I dont think you would even need to drill a hole in the MZ pipe for the set screw.
I have the adjuster set in the middle of of the pipe right now and it was a good reduction in sound at low RPM. It is still too loud though so I am going to bring the adjustment back a few notches and see what it does. Considering the size of the holes, I should be ablde to run it at the most restricted position just fine.
I am also thinking about wrapping the baffle with some fiberglass muffler packing and tying it down with some stainless wire.

It looks really nice, no cutting or welding needed on the MZ pipe. The only problem I have right now is the thing is set in there fairly tight so I am going to need a slide hammer to remove it to adjust. One note, I definitely need to add a lock washer and a drop of locktite on the adjustment set screw.
