Default ZDZ 40 RE header lenght

Hi, I have just received a ZDZ 40 RE (black head) and I'll use a KS-86 V-4 canister muffler with it.

Can you advice me about the header lenght that is required for this combo to work properly ??

Best Regards

OK now I know after some search that 25 to 30 cm is the best lenght

OK, for the people who are interested, since no reply coming from the "SUPPORT", it should be from 22 to 25 cm in lenght.

Seemed short, was there a length of pipe or cone inside the mufflers that would have given it about a 45 - 46 cm length?
How did it work?

My calculations were 35 to 46cm for best power from 8,000 down to 6,000 rpm.
