right I am thinking of selling my akropovic stubby end can and replacing it with a full akro system.Is it worth the extra cost,i was worried about will I be covered by my insurance company as all full systems say not road legal.I like the hexagonal carbon end can the best with the full system and will I need a remap as well as air filter?and will all the exhaust sensors fit onto the akro exhaust system without any mods.
