Motor Header

12 12
34 34
Back
UEL Header Design:
Motor Header
Front
12 43

This would make the runner length of the front and rear cylinders different. I am not sure how it would affect the sound exactly though. |
I believe what Shiv is saying is that with the turbo you get the same sound with an UEL or EL, because the turbo is in the gas path. With NA or SC it makes a difference, but not with a Turbo. Though I could very well be mistaken, I believe that's what he meant.
