Just got my ZX3 on Friday, drove all weekend, and Monday the CEL came on. Took it to Autozone today and scanned it and turns out its a bad cat. Now I`ve been looking at long tube headers and the shorty headers, and trying to match up an exhaust with them, but I haven`t had a chance to jack the car up yet and look to see how the whole system is run. How would I go about doing the long tube, with a cat due to emissions in my county, and full exhaust? Would I have to get a universal and have it fabbed up? I`d much rather get a true bolt on system cat and all.
