ktm 65's are pretty much as good as you cant get when there stock, although you cold adjust the jets a bit and get suspension upgrade. the ktm exhaust pipe is the best some say although fmf do a slightley thinker versionn as sometimes stones pentrate the stock pipe. butthe again some say a hgs exhaust or such like fmf or pro circuit.
The FMF Fatty pipe gives you the best all around powerband. If you know about the stock pipe then the Fatty is a lot like this. It doesn't take any power off the bottom end, but enhances the top end and gives you quicker response when you open up the throttle. It is good all around because you can ride offroad and still do motocross. This the most popular pipe out there right now. It all depends on what you prefer and what your riding terrain is.
