There are numerous formulas and equations available to be found for calculating exhaust header lengths, but they ALL HAVE SERIOUS FLAWS. For example one of the BIG FLOPPY'S is that they DO NOT ALLOW for the INFLUENCE of EXHAUST GAS TEMPERATURES (EGT) to be incorporated in the header dimension calculations.

EGT (Directly determining wave speeds) is one of the most important aspects in designing an efficiently working exhaust header! CORRECTLY DESIGNED HEADERS ensure that the negative pressure component of each exhaust pulse reaches the exhaust valve when BOTH the EXHAUST & INLET valve is open (Cam Overlap Period), thereby assisting cylinder scavenging.
