Meh. Test pipes are rasp-y and smelly, I would rather get HFCs. Also, I don't want straight pipes, it's way too loud.

Art pipes and high flow cats are illegal in Ca., but can be allowed if they skip the visual inspection and you're not throwing any error codes! But I didn't tell you that...Gary

Wait, didn't you answer my question like half a year ago? :P

HFCs are going to be less smelly than Art Pipes and Test Pipes though AFAIK, plus I like the sound better.
