I'm going to install my cats on my off-road x-pipe this afternoon and I have a quick question. First off, I just bought this car about a month ago so I don't know much about these x-pipes. The owner sold me the car in the 'off road' version. What direction does the cats go on the x-pipe. I know where on the x-pipe they go but not what direction the cats point (to the rear or to the front of the car).
