hi guys i just joined. i am currently designing an exhaust for the blaster 240 vitos kit with the intention of creating a new line of exhausts for sale. id like some input as to witch rpms work best for you guys and what is the best diameter of the exhaust outlet to start with. i am also leaning twords having the kit include a ported cylinder to match the exhaust pipe (a 2 stroke exhaust that is not tuned for a cylinder is useless lol). id just like you guys opinion and input as to what you all want. sofar im leaning to a high rpm exhoust since the blaster has little tourque coupled with either the stock cylinder or a vitos culinder ( or one for each, hmmmm ) i need opinions guys...
