Woah. It didn't rattle any of my heat shields .. The only thing I could complain about is the gaskets for sure. Exhaust leak after about 6 months of having it installed. I just went with some ebay one and put some liquid gasket all over it, and it's all fine now for about 3 years.
Lol, you're not going to go back to jail for an exhaust .. And you don't live in california so I don't believe you have to worry too much about an exhaust .. Cali police will just pull you over for anything and everything ..
