While taking some measurements of my cat back exhaust today (I have a modification in mind), I notice that the inlet and out diameters on the mufflers seemed quite large compared to most of the other aftermarket mufflers that I've come across - 3.5 inches (inlet) and 4.5 inches (outlet). I am curious to know this compares with some of the other aftermarket exhausts on the forum .

p.s. Despite my penchant to be bawdy, this is not a "size matters" competition.
