Some did and some didn't. I have the same vehicle with dual tanks. If it didn't come with a converter, these are the things to look for. Under the hood there will be a sticker that says no catalytic converter, the filler spout will be oversized for the leaded gas, and there will be no marking under the fuel gauge that say UNLEADED FUEL. All of that no converter.
