Which one is better design for the CBR 1000. I am looking for performancenot to concerned about the sound . All feedback is helpful................ Thanks

 

neither of the 2 for performance.

arata, sato, akra.

 

from all the reports and dyno charts i have seen, the leo and the arrow will perform on par with the arata and sato.

however for the 1000rr if you want a good performing lightweight cheap exhaust
go to www.ridersinc.com and buy a full hamaguchi

it is 900 bucks, completely titanium and gives the same hp increase as arata
