Hi, so I’m an X Corrado junkie, newly turned GTI Lover ! I recently bought a 2002/ 337 edition 1.8 T 6 speed manual. Anyway, was aware of the 2.5 techtonics exaust. Didn’t realize I don’t have a cat, just a straight down pipe. “Blonde moment” until my second emissions fail, that said “ not supported “ down the line. Now my question is this. Was the car “tuned” and WTF do I do ? Outside of spending a lot of money and having my beautiful exhaust cut, to throw a cat on ???please help. Baby is parked, because my sticker expired.
