Mike, I saw this on the BDS (Blower Drive Service) web site under FAQ section and thought of you...
What kind of headers should I use? Steel, or stainless steel headers may be used. Engines with 400 CID or less should have exhaust tubes at least 1 3/4 " to 1 7/8" diameter and larger engines should use 2" and bigger. Forcing more air into the engine with the blower requires more exhaust to be passed through the exhaust system.
