Thinking about getting the one's that were the same as the 65115-98b Screamin Eagle Performance mufflers. All I need are the baffles, I have a set of cans and end caps in pretty good shape.

How well do they flow and tune with stock headpipes? I don't expect them to compare to the top named 2 into 1's but how much would I be giving up if I chose these over my tired old Fatcat?

Not knowing what stage your bike is in , Ive seen stage1 with as much as 7 - 10hp bolt on  over stock headpipe with the FC . So I'd feel safe to say you'd take a 7-10 hit....xzo
