I am sure that this is going to generate some snickers, but here it goes!
What I think I know:
90 degree crank V-8's do not generate equally spaced exhaust pulses in each bank. In order to improve scavenging, some systems incorporate an H pipe or X pipe to interconnect the exhaust systems of the two banks. Considering only the X pipe for the moment, this is my question.
Once the flows are combined at the X, why are they separated? In other words, why not a Y instead of the X? Rationale: If the flows have been "combined", continuing in a single pipe should be lighter since the circumference of the single pipe with cross sectional area equivalent to the two independent pipes will be smaller than the combined circumference of the two independent pipes. Additionally, since the circumference is smaller, there is less surface area to create drag on the exhaust flow.
I am not interested in becoming an exhaust system expert. Just trying to understand.
Thanks again, I will retreat to my bomb shelter.
