I know there is a lot of discussions about which pipe to buy for a raptor, but most of them are about a raptor that has been highly modified. I was thinking about buying a pipe for my raptor, but the only thing I have done to it is put a K&N air filter in. I have read the other discussions and learned that if I put a pipe on with the K&N, then I have to jet it also. So, here is the question, what would be the best pipe and jet kit for me to use? I basically ride trails and some home-made tracks. Thanks.
