First Update

Mini bike 0 to 30 times / stock exhaust vs header pipe / Predator 212 Tested the minibikes 0 to 30 mph times with a Dragy GPS performance meter. The Predator 212 is stock except for an aftermarket air filter and the governor removed. Zero to thirty times tested with the factory muffler and then with the header pipe to compare the difference. I'm not really sure what brand the header pipe is. It was an old pipe off of my go-kart. I cut and shortened it to fit the minibike.
