One might notice that General Motors' highest-performance Corvette engine closes off half of it's exhaust system during cylinder-deactivation in order to 'protect' back-pressure for the half of the cylinders still firing!
Is this 'Unicorn Corral' material?

For the PWTB:
NO it is not.
Plz feel free to discuss that with David Vizard himself.
(You have heard of him haven't you..?)
He's active on YouTube and various forums IIRC.
