I put a pic in my gallery, can't figure out how to post on yet? Mine was also too quiet at idle but now it's just about right. If you want it louder drill more holes. I actually was considering changing pipes till I did this, figured what the hell if I still don't like it Ill change. My buddy put 8 holes in each onhis M109R a couple years ago, that's where I got the idea from.
It's really no different then changing a baffle out in a pipe, I heard that riding with no baffle would hurt (no back pressure) but don'tthink there's much truth to that,What about drag pipes...
