What are the pros and cons of removing the cat? I have removed them off a 3.0v6 and a 3.4v6, mainly because at the time it was the thing to do. Here is SC we dont have to worry about emissions. I now have a 90 4x4 with a 22re 170k miles that runs like a top. I know it gets clogged and all but serves a purpose. Would you cut it or not? why?
