Your pretty stupid about it going 80mph. It tops at 67 with stockgearing. The pipe doesn´t give you speed. It gives you like 3-4 horse. Wow. It all depends in the sprokets. Why did you even mention the pipe ? That´s the worst representation of race ready parts. It comes with vforce3 reed cage and valves and if I´m not mistaken it comes with a special piston with some kind of layering on top for extra durability? I heard that somewhere.
