When is the diameter to large? For example, when will the diameter size of the headers be to large thus decreasing exhaust velocity? Kind of like putting to much or to little of a kink in you water hose?

good question, Rob.
When I had a 500 cube street/strip car with about 600 bhp, I went to 2.125 inch header tubes(pre-collector). I actually lost power from the previous 1.875 inch setup.
#282
Thanks for the reply, I am really interested in knowing more about this information. I am currently using EVOMS GT 700 headers, but as you might or might not be aware they were damaged two days before Supra Nats when my car had a blow out and crashed. I put some liquid weld on them for the Supra Nats, which really didnt work so I am searching for headers more importantly the most effecient design.
Thank you
Robert
Thank you

Could you please explain the benefit or lack thereof in having equal exhaust travel lengths of the header tubes? I was under the impression that it's important to have the same length of travel so the exhaust pulses don't interfere with the other cylinders on their respective bank.
