New to this site as member but I have years of experience with marks but i have a question that I haven’t gotten a straight answer to. In a couple of years my 98 mark is going to emission exempt in my area and I was wondering about eventually having a free flowing exhaust installed. I'm thinking headers, true duels, x pipe, and maybe some decent sounding mufflers. My question is has anyone ever removed all 3 cats? Every time I try to look it up the only thing I can find is about removing the 3rd cat. Has anyone ever did this type of setup on their mark? Or just removed all 3 cats?
