Doug,
It could be a combination of the everything. I'm not sure if the
Pacesetter is a 4-1 or 4-2-1 header. I have a 4-1 with a stock
main pipe tied to a GT6 muffler. It is really rather quiet, even
with the OD on and in deep water. With the stock manifold and
exhaust, it was only a little quieter.
