I just purchased a really cool 94 LC with all sorts of heavy duty off road equipment. The former owner just abandoned it and I got it at a city auction. Unfortunately, I've discovered that he removed the cat converter which is going to cause me issues here in Phoenix. I've looked at a Haynes book and it looks like there were two converters on it originally. Is that correct? If I temporarily replace the muffler with another converter, will it be super noisy? Any suggestions?
