It ain't whistling dixie no more.....Or....it doesn't sound like a old VW bug any more either.I was told it sounded like a ATV (ouch!!) and another "friend" said it sounded like his Dad's old Beetle (I admit that it did sound like that whistle the old VW's had just over idle and at a easy cruise speed. )
Had a day off (had to burn up vacation or lose it) so mounted the Dyna muffler I got on Ebay.It's a little louder than I wanted but it does sound better.It "sort of" bolted up. I didn't get any mounting hardware with the muffler so I had to make a threaded piece to slide into the Dyna muffler mounting bracket to act as a nut. I used a piece of flat stock steel 1/4 "(zinc plated) and drilled a hole and ran a tap thru to fit the bolt I had. The stock doughtnut exhaust gasket was too thick so temporarliy used aluminum foil that I folded over several times and then wrapped around the header pipe (not sure where I'm going to look for gasket material). I reused the factory heat shield so I had to make a bracket to hold the back of the shield (normally mounts to factory muffler).
Here's some pict's of the mounting . see bigger pict at:

Performance ? ? ?Stock'01 pilot jet, and a 150 main (thanks Lancer) with white spacer mod using washers (three metric washers from an old computer (hey, it's a good use for for the old clunker's)). Adjusted the pilot screw after warmed up, also had to adjust the idle a bit.
Well,... when rev'ing the bike it does give some black puff's....but it didn't get black when running. Actually is a nice gray color. I think the puff while rev'ing is the fact that the slide is not perfect and doesn't get down fast enough on a quick rev.
Back fire? ? ?......only if I get on it then let off otherwise it does not back fire on deceleration. It is much more throatier on deceleration.
acceleration: Hard to say....but I do notice that it seems better when I lug it (2K rpm's on the tach). Before it sounded like it was almost pinging or knocking....
Other than it's a bit louder than I wanted, I am happy I did it.
