Mine is a 01, i got it all from starcycle in the US.

There is 2 Carbon fibre slip ons with different part numbers, you can see them on ebay.

As to how different they are I dont know. There is apparently a street version and a race version???

I also got the power commander from them for like $240 or something like that.

The mapping I am running is 108-016, the email they replied to me asking which I should use read;

Most slip-ons will require a very similar fuel curve. The addition of an
aftermarket filter will NOT affect the fuel curve. Map 108-016 should work
fine for your setup. If you have any other questions please let us know.
Thanks.

pretty much same answer I got when I called them last year. I dont remember the exact map they gave me, but it was close, I tweaked it a little here and there.

I think the major difference between the akra street and race can is that the race is much louder. IIRC, they didnt make hardly any difference on performance, just alot louder

 

I dont think any power difference between them, i think one is supposed to be a little quiter thats it.

I think they may also call it a open system or something. Mine is not even that loud but it sounds

amazing, not ***** just sounds tough!
