 Is an exhaust without a cat legal anywhere in the USA?

where you dont have to have emissions...  i have gutted the catylitic
converters on my daily drivers (no flames fom greenpeace members please) . the
cat is still there, but its hollow inside. and since i dont have to have
emissions/smog check where i live, then its not an issue. there is a slight
increase in HP due to reduced backpressure.
also, on vehicles which previously had no cat, its obviously ok to go without
one.
