I have been a fan of Akrapovic for over 10 years now, using either slip-on or full system exhausts of theirs on 5 different bikes. The only exception, was I put the Termignoni high pipes on my wife's Capirex 620 Monster.
After waiting for months for the Akrapovic slip-ons to come off back-order for my "07 Aprilia Tuono, I went with Leo Vinces. And they have yet to make a pipe for my wife's Triumph 675. They have released pipes for new bikes just coming out, and STILL nothing for the 675 that came out in '06.
I'd love to see what they make for the Hypermotard, but I won't wait for it this time.
Pardon my rant !
