Selling my Akrapovic from my 2013 Fireblade. Believe this will fit any Fireblade prior to when Honda moved the cat from the standard exhaust on pre-2014 models to the end of the headers on 2014-on models. This Akrapovic is the version with the integrated cat and flapper in the (s-bend) link pipe - your experience may vary but I found this version to work far better with my bike than any others or other brands. Straight-through link pipes do tend to make more power, but are quite rough and 'hunt' around idle. Oddly, a Yoshimura exhaust I tried on my bike prior to the Akra also did the same thing. The flapper valve on this exhaust works off the standard exhaust servo - you don't have to use it, but found that my bike ran better when I did. The can is in excellent condition with no scratches or cracks in the carbon. The link pipe has also been laboriously hand-polished by my own fair hands so you can see your face in it! Totally unnecessary, but looks so much better when on the bike. These are £600ish new - this one is for sale for £375.
Forgot to mention, also comes with the carbon strap, bolts/spacers/washers to fit, and the original Akrapovic exhaust springs.
