im jus wondering something here, would a turbo manifold work as a header on a n/a car, if u were to weld the downpipe to a flange and bolt it all up, im thinking it would create a lot of back pressure due 1 and 4 exhaust ports hitting the 2 and 3 ports that are coming directly out,

but none the less if anyone could jus give me a little bit of a insight on how it would work, and wut i said is right about the flow being all screwed up by 1 and 4 ports

.... Buy a header, I believe it would be much cheaper.

it would absolutely create a lot of backpressure. a turbo manifold and N/A header are completely different designs. short, stubby tubes collecting abrubtly into 1 vs. long equal length tubes collecting smoothly into 1. if you're not going turbo, just get a normal header.
