dual exhaust

And yet again you declare your correctness without offering any basis for your opinion whatsoever. Just throwing out physics terms you learned in high school.

I fail to see how he's an idiot for developing a system to scientifically test the effects of backpressure on power production in an engine. Perhaps you'd like to explain why you "suspect" that the 65mm header on the KA causes a "venturi effect" when paired with a 3 inch exhaust. Maybe you'd just like to explain what the venturi effect is, and while you're at it explain what the venturi effect has to to with this statement(which I also don't understand)
"a 3in exhaust will make power with minimal to no loss at 100% throttle HP / Torque."

Teach us, oh wise one.
