Interesting, I'd never thought a exhaust would cause to high of static
compression just by eliminating the cross over.
As far as dyno it shows that cross over isn't important. Jerry Branch of
Branch heads studied a exhaust with and with out. His words out of my
book.We removed the pipes and plugged the crossover tubes, this showed
almost no change at all in the power. But would probably show up on a
emissions test as diluting the unburned gases somewhat.
Good luck, my server is off tomorrow so I won't see a reply as to how much
more you gain, or not gain I'd get another opinion.
