Hi,there is a pdf file from akrapovic,very helpful,but i cant find the way to post it to my reply.
Google this to find it:Brochure Akrapovic installation ligne 2.1.2
Recently i did install the at300.Make sure to fit the probes at nearly the same distance,and be very careful with the wiring(autotune guide tell you witch wiring is for the front cylinder and witch for the rear)
