Well, not all rings are going bad at the same time I would imagine. Unless the engine experienced bad treatment such as the wrong oil or the like. It would just be one bad cylinder in the bunch? Hence my tail pipe question. Did this come on suddenly or gradually? Is it running smoothly?
So given that both pipes put out the same amount I would suspect it is a common to all cylinders problem.
The oil pan should be under slight vacuum driven by the plenum attachment. Have you pulled off all these hoses and see if they are backed up? Did you pull off the plenum and look down the throttle bodies. Any of them particularly dirty?
