I own a 2005 4x4 Titan. As we all know the truck has a set of primary cats and a set of secondary cats. My nissan service center sadly does not believe that the secondary cats are cats. They say "its just a hole through the pipe". Does anyone have an official Nissan drawing that clearly lists them as cats? I'd like to prove to them that they are completely wrong!
