Default Is this possible

i've been thinking of removing my cats but don't want a federal offense for takeing my cats off so i was thinking is it possible to gut my cats then grind a hole big enough to put straight pipe through it then weld it to the pipe so it would be a empty cat over straight pipe. a "cat sim"

there is a company that makes cat simulators. They are shells that look like a cat. simply slide over a straight pipe and use tubing clamps to hold it on. I've seen them before.....ill see if I can find them.

I'd be interested in hearing about these if you know where to find them.

one way they could get you is with a temp gun (if they really wanted to) just look at the temp in front of the cat and temp at the back of the cat same temp front and rear= no cat/bad cat
