This way WAAAYY back then guys! The speed of the quad has about doubled with a 115 main jet and a straight pipe. For a while, I drove it with the stock quiet af muffler and a 98 jet. Then I drove it with a plucked baffle and no jet, it ran very bad like that. NOW we simply chopped off the muffler and put a 115 jet in it.

This is proof backpressure sucks guys. It's (the ATV) a whole lot faster with the straight pipe and rejet.
