Hey guys..I was playing around with this desktop dyno program..and I saw that Large tube headers give alotta power..can anyone give me some examples of some namebrand large tube headers, as in who makes them, where, how much?

Thanks in advance..

 

Stahl is one company that makes some pretty big headers that I can think of, they make true equal-length headers with primaries from 1 5/8" to 2".

Keep in mind that your idea of a "large tube header" might be different from the program's. Your results will be closer if you underrate your exhaust by one or two steps in the program.

 

Actually..I've got no idea..I don't know alot about this motor stuff yet but I'm learnin'..I also saw that small tube headers give about the same gains from stock soo ;>
