Hey guys I am new here. I just bought my 92 ford ranger about a month ago. It's in darn good shape and I only paid 400 bucks for it. I've replaced the radiator, thermostat, got 4 new tires, spark plugs and wires, wiper blades, etc. But I'm damn sure that my catalytic converter is clogged because the truck won't go fast, struggles up hills, exhaust smells bad, etc. So I plan on replacing the catalytic converter along with the rest of the exhaust system and I'm wondering what size pipes come on it stock? And if anyone has any advice. I was looking at some kits on summit and autoanything but my inspection is up at the end of this month and I need to get the CC and the muffler taken care of as well as some brackets and stuff to pass.
