Would gutting the cat give huge power gains? I mean if I had an exhaust, and I gutted the cat, do you guys think it would give me like 10+ hp. Also, would it make my exhaust louder. I'm asking this because some day I plan on getting an exhaust, and I was thinking about gutting the cat. Of course I would have another cat that wasn't gutted to put back on when I had to do smog checks. What do you guys think?
