So my cat is plugged, and I need to either replace it, or hollow it out. It looks like it would be a pain to hollow, and the new ones are out of my price range right now. Even looking at O'reilly's at the universal one is over 200 bucks. Any options for getting a cat that is not gonna break the bank. ZZP is showing one for 60 bucks, but I don't know how I'll get it on there, I don't have access to a welder. Could I clamp it on?
