I think there is a bit in that. there are a lot of headers made on very high performance motors that are not equal length. On decent 4 into one collectors they arrive in order so that they fire one after the other in a circular motion, on v8`s with the gt40s they go to the grief of a cross over to put them into the right sequence. A lot of 4 int 2 into ones are not equal length. Those large radius bends on the exhaust were done by an old guy by sand filling and teasing them round by hand with a blowtorch , hows that for skill and patience/
