Okay, okay! So they're FOUR strokes, but the principle is the same.

Acoustically speaking--and this is what it's all about--the action is similar.

ACOUSTICS--that's the thing here. Two or four stroke, exhaust pulses are being used to draw exhaust out (and air in). Be it an expansion chamber, megaphones, or the simplest form (drag car headers) the acoustic principle is the same.

No, 1200cc is about 75 cubic inches. That is a (1.2) liter w/135 horses.
At 2.4 liters that would equate to 270bhp if one looks at it for relative power per displacement. That's pretty impressive for a standard production engine! But it is an odd cylinder # with one chamber. I have heard that three cyls don't usually need a chamber because of the pulses from each other makes up the needed resonation. It appears that there was an engineer that thought differently.
The tri-Y type headers are an attempt at equal distances..
