Talking about exhaust notes, I have mentioned this in the past when comparing my smm to a stock Winder muffler.
My riding buddy and I, were playing on a big trail with some nice rollers for some decent air time. We were taking turns making sure the way was clear for one another on this 1/4 to 1/2 mile run. As he came by with his Max Spool 16 stock muffler tune, I remarked how surprised I was with it’s loudness, and the fact that I could tell he was turning 9K rpm, besides laughing at his air time during his high speed run. So we ran that multiple times with each sled taking turns, and what we heard was this. My Max Spool 16 with smm turns the same as his @ around 9K, but sounds as if it’s only turning 6K or so. His stock exhaust note has a higher pitch sound to it and you can hear every rpm note, making it as loud if not louder sounding then mine. My smm is louder at idle, but at wide open and going by someone standing there, the deeper sound does not allow for full rpm sound or notes! Never noticed that before!
Anyone else?
