This will be interesting! I've put 3/4 in dia tubes approx. 2.5 inches long in several mufflers. Always blocked off the stock. Problem is quantifying which of the mods made the most difference.... compression changes.... intake port mod... muffler mod...which ones? Have a 350 vid coming out in a bit. Found out a 1194 no base gasket build makes a significant difference.... or was it the muffler mod???  When its up take a look and maybe you can figure it out!
