You should find out whether a 4-2-1 or a 4-1 header performs better on an N/A SR.

that cusco is one strange looking header.

this will be for a supercharged sr. in a 91 240sx. my boss says that a 4-1 is better for supercharging, hes been building blown motors before most of us were born. so i tend to believe him.

I'd get the cusco one just cause it looks badass. That's all that matters right?

No, I think it's "brand loyalty" and the wow factor that some brands have

the 5zigen one has a strange design
Three outlets flow into one, and the 1st cylinder outlet flows on its own to the downpipe.

the Cusco one looks to be equal length, unless it bulges out for outlets 1 & 2. however, i don't know what that inlet/outlet tube is cause its not for EGR
theyre more commonly used on 4age and other N/A cars though

both headers function for different purposes. it all depends on your goal
