Is this just me getting used to a boxer after driving inline motors (BMW, Honda, Toyota) for years.

equal length headers, what you are feeling is resonance, when 2 waves of air meet they amplify the wave when going in the same direction.
you are feeling the resonance though the seemingly inexistent sound deadening this car has.
My last car i had it modified to run to 9800 rpms... sounded like it was going to blow up every time... even though i must have hit the fuel cutoff maybe... dunno 10,000 times... i had PPE equal length headers on my last car... ended up with the same result
