ok heres the deal i was looking at the specs. for the DMC alien exhaust and by what i have seen i like the look of the torque curve and hp gain so my question is this? i am adding the whole DMC alien exhaust pipe system and also have an K&N Air filter that i would like to run both together but with the alien exhaust i don't have to jet going by the specs. just only have the air box off. If anyone has this or has some suggestions on what i would get for the jet kit and settings i would like to have some feedback on this. I have just about got through all the breaking in of the yfz and the pipe will be here in about a week. My basic question would be this: What settings would i need to run where i live at in northern georgia for the altitude and with the k&n filter with the alien exhaust? THANKS FOR ANY COMMENTS LEFT!
