Figuring I had not much to loose (except a tip for my friend at the muffler shop) and something to gain (the possibility of a better sound), I took the "Mythbusters" approach and had a 2.5" section of tubing joining the catless mids, upstream of the stock muffler.
My friend pulled the exhaust muffler and showed me the unobstructed, straight-flow configuration, indicating that without some backpressure there would be very little, if any gas transfering through the "H". He advised against it, stating I might not get the effect I was hoping for... but I asked him to proceed.
He tack welded a jig before removing the mids, carved out a half semicircle from both pipes at the point where they come close together, masterfully fabricated a crossmember that fit perfectly over both holes, and layed a nice weld bead over the joints.
The results:
Seems my friend was correct, in my perception the sound remained exactly the same in quality and intensity, and the popping on deceleration was unchanged.
Myth busted!
