well, if the inside diameter of the opening of the pipe is smaller than the exhaust port of the engine, then it would cause turbulence and a choking point, so yea it would probably help a little, but is it a stock pipe or aftermarket? if you want good power w/o spending too much money, get a used pipe, decent air filter, reeds, and a jet kit off of ebay. remove the airbox lid and jet accordingly, the jet kit should have instructions as to which jet to use for what setup. if your running crappy 87 octane, go with premium. it'll make a difference.
