The OBX header has 1.75'' primary's/ 2.50 collector, I don't know the overall lenght thou. I went w/ FWerk's header/flex & added one of their stealth muffler's. So I'd say the OBX would work better on a 20 motor, for low end grunt, say for a atx car. I don't know the primary lenght thou, I say that would make a difference= say w/ a stick/auto, you would want to add a few more inches to a auto primary lenght, to make up for the converter. It works that way on V/8's, maybe not on 4 cylinder's.
