What are the penalties for running an off-road mid-pipe here in California. I know that California has one of the strictest emission laws in the country. But what can happen if I get caught? Is it just a fix-it ticket? I love how the Mac Prochamber sounds when combined with some flows. That is what I want to get for my ride. I just got some 2 chamber flows welded in & it just doesn't sound loud enough for me. My mid-pipe seems to be the problem. I'm running the stock H with 4 cats. I need to get rid of them asap.
