 Does this cause too much back pressure in your Fister as he blocks the entrance to the muffler a bit?

I didn't have the right nomenclature-google "Grainger 3/4 knockout plug" as an example. Common electrical box plugs. With them in the Fister bypass is short circuited, and the OEM muffler is working as designed. W/O the secondary cats it's a nice improvement over the US sound (probably what the ROW 2 cat 986's sound like).
