I have a 2002 kawasaki kx 250. It just has a stock pipe on it. I want to get an fmf pipe. I don't know whether to get a fatty or a gnarly. I ride everywhere. I ride at the sand dunes, i race, and I do hillclimbs. Which pipe would be better for me a fatty or a gnarly? And what are the the affects of both pipes.
