    I Need help picking out exhaust

    I have an 04 Kfx 400 and I was wondering what is the best performance exhaust for it? And is it worth paying more for the full system?

    I've read in magazines that HMF is supposed to give the best performance, but their are a lot of people who run Yoshimura and say they wouldn't have it any other way. Plus a lot of the pros rode with it. Personally I think it's all about how much you wanna spend. They will prolly do the same thing with same performance.
