The key is the axle weight 6500 lbs and above not required, below required. If he has a 2wd, which was not specified then he may need cats, if its 4wd he's above the 6500 lbs and does not need them. I have a 78 3/4 ton that has not cats, came from the factory that way. It has a 454 and always passes emission right in the heart of phoenix.
