1-4 and 2-3 gets my vote, it just amkes more sense; backpressure is going to build up big-time if both 1 and three are going off after each other, into the same downpipe ... seems as if you would want 1 going off, then 3 into the other set, then 4 into the same as 1, and finally 2 into the last pipe, nothing builds up as pressure ...
I guess my real question would be; what exactly fits our engine, rather than which one uses the correct order? Any clues to something we can find relatively simply? (as in; go to this website, click add to cart, install)
