hi guys I have an audi tt MK2 2007 3.2 vr6. I am trying to extract as much sound from this beautiful engine as possible, I have a milltek catback but I want to remove the two catalytic converters restricting the sound. I've searched everywhere for a pipe to replace the pipe with the cats on it. how can I decat my car? p.s I have an mot guy who will pass my car without a cat. thanks.
