Live and learn gentlemen. I went with the jardine slip on on my xb9sx and it wasn't loud enough so I'm getn the D&D slip on in late feb. or so. You may not want the loudness like us obnoxious types but it's better to just save up and get what YOU want, even if you have to wait a little longer. Pinch the pennies where you can and make yourself a "bike fund" piggy bank. Comments? Comments?
