My choice for my 10 was the Yosh slip-on. I also added the 94db insert which eliminated the spark arrestor. This setup gave me the added top end rev I was looking for without giving up any bottom end. Great sound and quality too.

I too went with the Yosh slip on. Best improvement I have made to my '11 thus far. Better value over the Akrapovic as well.

can you guys post some pics? Are the Yosh's shorter than the stock pipes. I hate how far out the stock pipes set.

I have the 2011 version of the yosh slip-on. It is a bit long and heavy but of the ones I have tried, stock, drd full system, fmf 4.1 slip-on. This one offers the most performance in my finely tuned seat-o-the pants testing. And the quality and fit is the best also. As a side note I run with no inserts and the noise is not a problem to me. Way quieter than those stock raspy kawi exausts.:ride:
