You are silly. Illegal, who is going to find out unless they get underneath your car. I run with no cat but have stock mufflers to keep it quiet cause these cars sound like **** with loud exhaust. Then again to my ears anything thats not a v8 sounds like ****.
Pretty sure a cop wouldnt get under and check cause i dont fit unless its on blocks or somethin. Its more like my dad doesnt want me to do it cause its technically illegal. However theres at least 4 kids at my high school (of like 350 or 400 kids. huge school im tellin ya.) that have no cat and dual pipes with hardly any restrictions and the cop sits right outside the lot (yes theres only 1 cop on duty at all time in the town of like 785 people). The one kid cuts off his exhaust and strait pipes it and all he gets are those "fix it" tickets so he puts the cat on and takes it in for it to be checked and then goes back home and rips it off.
Unless you're drunkie slammered, you can get on your side and see your entire exhaust.
Also why haven't those people found the frozen boost cat yet?

Its not like high flow cats even do anything after two years.
They're install to pass e-test then discard.
