I just read the post on the reccomendation. It seems like the condition is to just not do it if you have cats, because it can damage them. Well, I'm about to change out my cat and put a new one in, so should I do this now? Thing is, what are the pros and cons of this thing? What does it do to N/As? Mine's an 88, using an 86 Zenki engine...
