      Is there a decrease in the pipe size from the header back anywhere?

      What size is the center radius for the perforated pipe inside?

        No decrease from header back to muffler

        Perf pipe is 1 1/2 to 1 3/4 inch and header is 2 1/4 inch.

          The 37.5 pilots are larger than what we get stock, but the same as the rest of the world. You will end up with the mixture screws farther in because of it. IIRC, mine are between 1 and 1.5 turns out from bottomed, using the same size pilots. The numbers of turns you see thrown around here are assuming the stock pilots.

          Well that should be good and quiet. Even most "street core" mufflers have a 2" ID core. Loud ones are usually more like 2.5".
