Has anyone removed the cat on the 14/15 model yet? Seen as they upgraded the engine from the 12/13 models and increased HP only to loose the gain barring 1hp with the addition of the catalytic convertor I'm thinking of doing so and wondered what the options are. Will I have to buy new race headers to go with my arrow slip on or does anyone know of a replacement for the cat only, i.e. cut off and use a sleeve?? Plus, I guess, is it worth doing? Cheers
