Hey everyone, I currently have a problem with my cats. They seem to be stopped up and need either replacing, to be taken off, or punch. Well, I'm a little strapped for cash so replacing is last resort. I still have stock exhaust on it right now, but I'm thinking about running straight pipes...I hear if you punch the cats they sound s****y.
I also wanted to know if I did end up either punching or just running straight pipes, would this effect my ecu?
