Quick update... Now that I've put a hundred or so miles on with the new pipe I must say the powerband is much different than with the stock. There is such a increase in airflow you can drastically feel the difference. Much smoother acceleration from 1st our through 3rd. I am getting a backfire during shifts, I belive this is normal. My friend at yamy dealer said a powercommander will fix that.
All in all it really does grumble similar to a ducati. I was worried it would sound like a R1 with aftermarket exhaust kindof tingy, but it is a nice deep consistant sound. Also shaves over 8 pounds off the bike.... not that I'll notice a improvement in handling, but a more experienced rider may.
My rating on the Two Brothers V.A.L.E Black Series Muffler - 2 Thumbs up!
