Hey guys. I'm planning on buying the Cobb catted dp soon. I've done some research and decided that since I live in a harsh winter climate with lots of salt on the roads that I would rather coat my dp than wrap it. Anyways I'm having problems trying to find good info on whether or not it's a good idea to coat the cat as well. Some say since on the Cobb and cat is far back from engine bay there is no need to coat the dp that far back. But with my climate I'd like to coat the whole thing. Is it recommended to coat the cat? Thx for any advice
