2004 yz250f jetting

I recently put a FMF exhaust on my bike and was wondering what kind of jetting I need to change. I havent had a chance to ride it yet so I dont know what its running like, but I was wondering if anyone had this pipe on their bike and what they changed. right now the jetting is all stock

From what I heard, you may not have to jet your bike with the header........

Go to FMF's website, I believe that they have jetting suggestions based on the type of exhaust you have etc...
