Because you would be dumping exhaust gases straight out of the motor into the air. No cat, no muffler, nothing. Just a straight piece of pipe pointing at the ground.

Most of the time you can still pass the emissions test because you will not be building boost. Any place that wants to keep their inspection licence will fail you for the visible inspection. Dumping exhaust to the atmosphere before it sees a cat converter is illegal. I run an O2 dump and somehow snuck through inspections . -Matt
