Mintor 1.70

[Henderson,Eric]

I am a bit confused on the pipe lengths that are being used. I measured my ES (OS-clone pipe) and the baffle is 13.5 inches from the inlet. The Bolly pipe that came with my Mintor has the first baffle at 11.25 inches. 

With the ES pipe I am at 24.24" from center of head with low rise pipe. What I was going to do was use the Bolly but elected to use the ES because it had an integral stinger/diverter.

If I now fit the Bolly I am thinking that I am going to be way-off in pipe length, Any experience out there with the Bolly and this header on a 1.70 Mintor?

Regards,

Eric.
