Which one is legal?
well technically any aftermarket exhaust is illegal in most states as the laws basically say something like "any exhaust system not originally installed on the car by the manufacturer shall Be deemed illegal" however Unless youre really loud, nobody will give you any trouble for it. difference between 18 and 12 is how much noise/drone go inside the cabin. 12 will allow more noise /drone in the cabin.
