So I’m looking to get stage 2 hot cams and a high compression piston. Would I need anything like better jets or a better header and exhaust if I have those so it won’t cause any issues?

 

Not better jets, but possibly a different size. With tuning, altering one part from standard, affects other things. you may find a less restrictive exhaust boosts the power too, but the silencer is more restrictive than the rest of the pipe on quads.
