Mike,
You obviuosly know what you are doing and are competant enough. Not questioning you. I wouldn't argue with you if it was the greves. No big deal. I have seen many people that didn't set up the 140rx header with the correct length for different pipes. It's not a problem with the pipes. It's a setup problem. Hard to blame the pipe. Even though the change in pipe cost you a plane. But the pipe itself works perfect when setup the way I have it. Ask anyone in district 7.

Es pipes are great and you will be happy with one Troy.
Good luck to ya..
Chris
