Not a fan of the BBRRRRRRAAAAAAAAPPPPP either. If I ever decide to "split" a stock manifold, I will skip the isolation plate between the two halves in hopes to eliminate that sound. My thinking is that leaving out the isolation plate will allow some noise elimination from the sound waves canceling each other out inside the manifold.
In other words, I plan on simply adding an additional exhaust flange to the rear of the stock one, and running another stock exhaust pipe/muffler/tailpipe. It won't really be a split exhaust, just one which breathes twice as much air.
