Don't lmao too hard!
It cut the noise in half.. and could be noticed from a distance as well as on the bike. Now because I got a taste of true quiet I have come up with other ways to accomplish this effect. This bike was a mutt for proving grounds. I have more efficient means for accomplishing this accidental effect now.. I do like the quiet!!!!!
This conduit that I used was rather too small in diameter..
