Well, it's that time again. I need to my 85 CJ7 smog checked this month and I need to replace the catalytic converter before bringing her in. I'm thinking of getting the Universal Cat from JC Whitney as it is $30 less than a direct fit one. However, they come in 4 different inner diameters: 1-3/4", 2", 2-1/4", or 2-1/2". First, has anyone used this type before? I think this is the one I used when I first bought the CJ. Second, anybody know which diameter I need? This is a completely stock exhaust system.
