It's hard to tell of course but that sounds like it may be louder at idle than my Muzzy with the quiet core and spark arrester installed. I'll try to do a side-by-side recording with my friends bone stock bike before we tear it appart to do the mods next week. I can tell you he came back from a test ride on mine grinning from ear to ear

 

man, I could kick myself in the *** for not recording the stock set up first before I just riped into it [:@] sorry guys [sm=headbang.gif]

 

that sounds just like my old 82 XR200. i like the music coming from that stock pipe, nice job and it was free too.
