Totally agree, it's just difficult to find a way to quantify the flow restriction of a muffler, short of back to back dyno tests, and to a lesser degree, track testing. I wouldn't imagine an aftermarket muffler being that big of a restriction, so we may be splitting hairs. I'd expect an open cutout to be less than a tenth quicker than full exhaust, does this sound about right?
