Catalytic Converter Problem?

You cats can hit the disagree all you want. That's the truth. There's no such thing as a high flow cat. They only advertise that because they make the inlet and outlet bigger than a stock production cat. Unless you enlarge the exhaust to the cat's inlet and outlet size, you don't get the "high flow" effect. Converter material is restrictive. That's how it does its job. I'm not even going to point to the THOUSANDS of links to articles online that verify this. Yall have the same internet I do. Just remember one thing when you want to disagree. I'm not selling products. I don't have a dog in the hunt. Believe what you want. A fool and his money are soon parted.
