A few have PM'ed me as to 'Why catted headers'?
We live in PA and they do 'visual' and OBD smog inspections yearly. We want to stay 'legal' and it helps me sleep at night knowing that my emissions are slightly better than non-cats. And the cats help pull some of the exhaust 'rasp' out. We can run with secondary cat delete (they are not required) and PE and still have reasonably tolerable exhaust sound. And everyone does the cat-less because it's cheaper and we wanted to be different.
