So I was wanting to get the best possible sound out of my 8 and I want to do equal length stepped headers that fire in a sequential order so does anyone know from front to back in order how the exhaust fires out the exhaust ports at the header. Thank you.

 

Just make front and rear equal length with the middle siamese as short as you can. That's about all you can do to separate the pulses , not that it will achieve anything.
