I agree. As one pulse travels through the collector it's inertia causes a low
pressure pulse in the other pipe which of course increases the exhaust flow out

You mean 60 degrees out of phase.  :-)

One pulse per 360 degrees of e-shaft rotation from each rotor.
The rotors are located on the e-shaft 180 degrees apart.
There fore the pulses are 180 degrees out of phase.
