Hello all...I have just recently purchased my 2004 CBR 1000rr and love it so far...A little rough on the wrist at first but im sure I will get used to it after a few hundred miles. I have some questions on aftermarket exhaust.... I am thinking of either the full system Yosh or the full system Akropovik. I had the Akro on a 2001 R1 and loved the fit, finish, and power gain. Has anyone installed the 2 systems on their bikes yet??? Here is a few things I am questioning:

1. Fit
2. Easy of installation
3. Access to oil filter
4. Dyno #'s
5. Seat of the pants feel
6. Power Commander or Yosh Box????

In the future I plan on doing the other normal mods such as steel braided brake lines, undertail and the etc. Thanks for anyones input.

I guess your 5 part question scared too many of our members. But I think the yosh and akra's are pretty comparable. Theres a big price diff however so it's really a maater of preference what you want to get. they both fit beautifully. the akra's one up on dyno results, the yosh has more seat of the pants feel, but i'd go for the power commander anyday. yosh is made mostly of stainless steel but akras mostly titanium. but then again, you pay for the respective materials. i dunno if this helps, or im just rambling, but it really is how much you want to spend.
