question regarding header & tuned pipe

[Ihncheol Park]

Hi, All,

I have a question regarding the header & tuned pipe.

I will be testing a really light Tuned pipe (Japanese F3A pilot is testing
the pipe on OS 140).  It is 550mm length, 48mm diameter, 18mm inlet
diameter.  38g for weight.  I will have to weigh it before believing the
weight of this pipe.
I believe the pipe is being tested with Hatori/OS header

My headers have diameter of 20mm ~ 22mm (Macs headers) that is larger than
the inlet of the pipe.

Does the differences in the diameter of Outlet of header and Inlet of pipe
make differences when tuning for the pipe?
thanks,

Ihncheol Park
