When I bought my kx500, it had an FMF Gnarley on it with a major dent in it that had rusted in a major crack. I wielded it together and put a piece of metal over it and weilded that on. It works fine but looks horrible (as my sheet metal work and wielding ability are...well.... I am a good bubble gum maker) and I am afraid when I start racing that it will not hold and I will end up causing major engine damage because I did things the cheap way. I have read the reviews on this sight about pipes and to be honest, I just want a stock pipe or an aftermarket equivelent. I am a woods rider and never run motocross so low and mid range power is important. If anyone has a used pipe that they would like to sell for a reasonable price, let me know. Or if anyone knows were I could get one for under 200$, I would appreciate the help. I plan on purchasing a new pipe sometime after christmas.
