the cat back is not important
what is? , is cat forward,
in fact, that is why they call it this, what end wrecks fueling, rates , cat forward.
that means 02 works and no air leaks or cracks allowed from the front "leading" edges of the CAT honey comb forward.
or the 02 slams to 0volts and ECU goes max rich and engine misfires.
sparks tops run black.
If cat melts engine power goes to hell, and vacuum acts totally CRAZY. (laggard and reversed kinda )
The EGR converts EGR back pressure into EGR Flow rates
the back pressure is engine load, in a very crude and crazy method abandoned forever in 1999, to now.
in all newer cars load is computed deep inside the ECU, (vacuum/rpm /tables, gears selected, fuel flows, maf readings etc) and egr super simple as door prize.
