The mufflers are 3 inch straight through with packing around them for a total diameter of 4 inch. They wont affect power output. They did quiet the system, but not in a tremendous way.
Its hard to actually determine noise level differences, because Im inconsistent as to my tolerances. The exhaust was quiet and awesome this past Saturday afternoon, but this morning to work it was annoying.
