well going by some of the pc3 maps that are on 1000rr.net site and rougeracing/hooligan sites, the arata/sato/akro are the highest hp yeilding slip-ons. they also posted up dyno runs with hp/tq numbers. now i was unable to find maps for micron, jardine, 2bro's, yosh so i cant compare those to the ones i found.

i found a sweet deal on an (used 1000mi) 06 akro c/f can w/ti midpipe for about 425.00 shipped. im just waiting for verification that it will fit on my 04. i know the 04/05 will fit the 06, but not sure if it will fit 06 to 04/05. on some cars ive modded you can swap one to another, but not the other way around.

I'd go with Sato. Check out the dyno chart at http://www.rogueracing.org/1000rr.htm . He has it on an 04 CBR1000RR. It is pretty impressive.
