Hey DNW.  I think I've seen you over on M-J.com.  This question is more appropriate for the Rubber Side Down section.  The Tech Section is for technical reference stuff.  RSD will get you more replies.  But to answer your question- not really.  Nor can you debaffle it like the M50.  But it's 100x easier and cheaper to replace the muffler than on the M50.

I hate to argue with someone like Jim, because I usually end up looking silly.  Nonetheless, you can pull that back plate off and the stuffing will pop right out in your hand.  

Here is the thread I put up last summer that shows I'm not dreaming...

I ran the bike that way for many miles, until the Jardine slip-on I won came in the mail.  It sounded much better than stock, and was reversible with about five minutes' work.

If you set the search screen to all posts and search on Hartman - you find the most famous of this type of modification to the savage muffler - always seemed like more work than it was worth - but if you lived in place where you could not replace the muffler such a thing might be worth while.
