What changes to your carb jetting were required after changing over to the 2 into 1 exhaust? 
Dropped the main from a 150 to a 142. Been running without the baffle & it has felt a touch lean off idle cruising.. Plugs look the same, but mpg went from 42 to 46.
I still have TBS needles with one shim (same as before with the D&D's) so for a trial, I cut off most of the baffle & drilled a few extra holes hoping the added back pressure solves it... If not, I'll be pulling the baffle and adding a shim.
