I am fitting a akrapovic can to my full austin system for the odd trackday. As it failed the noise test at brands a couple of weeks ago. I am now thinking of shortening it by about 75mm just for looks really. But I don't want to make it over the noise limit so it's going to be a gamble. I need to sort a hanger out as well. Once I have finished exhaust I am going to fit a 2012 seat and tail unit.
