More Triad, advice sought Options

[John Kelly]

The used Triad I got recently had something banging around inside of it so I cut a window in it to find out what was in there. There were two pieces of tubing with small holes in them welded together as some kind of baffle. Nothing to direct flow through the bottom leg of the "T"... the 1-2 side goes directly at the 3-4 side and they fight for access to the next leg of their journey. I'm happy to hear that folks like these mufflers, and will probably use this one since the engine was tuned using it, but I would like some advice on making a baffle, or "Y", or combination of the two to fit in window before I weld it back up. Pictures attached.

I understand that they are taking turns, but I'm thinking the path of least resistance is straight ahead, not around a corner, so perhaps the exhaust flow from any particular pipe tends to go towards the others until taken over by the increased pressure from the next one to pulse. Wouldn't this make for a lot of turbulence instead of a sharing of the outlet? In other words, it seems to me that none of the pulses would go directly out through the lower leg of the "T", but would go across the top of the "T" until forced by the higher pressure of the next pulse back the way it came and then out. If this is true, wouldn't it be better to have a "Y" type baffle at the top of the "T" to direct most of the flow out, or is some turbulence a good thing? Any thoughts about that?
