i can confirm that the akras fit. i have them. when i got mine, the claimed it only fit up to an earlier year. the Vee's exhaust has not changed.
have not added a power commander yet. other than a sweet friggin sound and decent weight savings high up, the akras have added zero to the performance and i suspect that over an equally tuned stock bike--PC or not--will do very little in the way of performance.
