I've always run Random Tech cats on any of my vehicles that have such a requirement. I recently put my 87 T-Type through New Jersey's emissions testing, and the car was so clean the tech thought something was wrong with the calibration of the machine. Random Tech has both 3.5 and 4" cats available in a couple of different styles.
