Thanks much for the comments on this report, Pe. I wasn't able to get much from the German, so I was going on the stats.

What do you think of the silent muffler stats? That is the one, for mounting simplicity and noise reduction, that I would choose, if it didn't cost so much in power. The MVVS ads say that this muffler gives a little increase over the standard muffler, but in this test an awful lot of power was lost.
