As opposed to, say turbo headers that have long primary tubes and snake all over the place before they see the turbo. Way more volume to fill on those before the exhaust gasses see the turbo.


I don't ever recall seeing a purpose designed long tube turbo header as you describe. I agree that the volume might be similar, but I bet there is big difference in exhaust gas velocity when comparing a large log style ala the OP's latest bargain project vs an individual tube style tuned turbo header.


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
