My 93 chevy Silverado z71 4x4 doesn't have an exhaust. My question is how many catalytic converters should it have?

I looked on Parts Geek for your make and model. The exhaust is a single straight pipe to a dual pipe muffler. It Y's off the back of the muffler to the left and right side of the truck. It looks like the exhaust bolts to the back side of the cat. So I would say there's only on cat on that truck. What do you have left? Just the manifolds and that's all?

Go to and put in your truck's information. Click on exhaust then muffler. Choose the Walker muffler and click the blue info icon. A complete diagram of your exhaust system with part numbers will pop up. HTH. -Jim
