Gunter's debaffler

I used a 1-1/8" hole saw first to allow the inner dimension of the extended hole saw to pass over the inner pipe of the exhaust.

Then I used a 1-1/2" hole saw to remove the rest of the material at the end of the pipe.

And then the "debaffler" or extended 1-3/8" hole saw to finish it up.

The result is a nice, modest rumble at idle, more authoritative growl during acceleration and still fairly quiet at cruising speed. I am happy with it. I can hear the bike now over the wind noise but it's not the loud droning roar of most HDs. I did notice a little more vibration in the bars and pegs but I don't think it is anything that would bother me too bad. I haven't noticed any performance gain but I still need to adjust the A/F mixture as all my mods have had to do with breathing. AI removed, snorkel removed, baffles removed and soon a K&N filter.
I sent the debaffler on to Lazyrider, so if anyone wants to try it next send him a PM.

I don't know if these pics will work or not, if not can someone help out? -thanks. I posted links instead.
