In fact, most headers made for modern V8s are of the 4-1 design...short or long tube. It's not that they don't benefit from such designs, it's that people have spent so much time working on V8s they've had time to sort of tune the length, tubing diameters, and designs. I4s are, in the grand scheme of things, relatively new to the American performance market so people are still playing catch-up. Maybe instead of dismissing all of us who drive cars with V8s you consider that maybe some of us know our shit. I have yet to see you point out a single reason why a different way works better or why one of us is wrong.

i've pointed out basically the best header out there for our 1.6ltr engines which is a 4-1 design and makes power all over the rpm range.
