There are no flow issues, the 3”is too big; but I already said you would be unhappy with it, I don’t think the 2.75” 60608 mid is going to fix that. The stock header is only 2.1”ID with a lot hotter gas (gas law) so the 2 and 3/4 presents no restriction till you are say 800 up engine HP and even then it ain't huge. I further restriction and 3” is just too big for your power level. Hope you got the S type muffler? Your still thinking flow and even the stock system with 1/2 the flow was good enough.
