The other question I have for the pipe gurus - I envision that we need to avoid leaning the top end all the way because as the motor comes on the pipe, the ratio of air to fuel will change and the motor will lean out a little bit. Does this sound right? This is my first tuned pipe and I'm keeping an eye on temps just for that reason...
Henna, yours will be a little longer like you said. I'll have to measure mine next time the cowl is off. DA should be able to give you that measurement really easily.

Header to pipe spacing - again I will have to measure but will post pics which may also help. I made sure that the coupler went over the bump in the header so that the clamp was entirely on the engine side of the bump if that makes sense. Didn't want it slipping off.

How do your temps compare to mine? Mine is running nice and cool.
