July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Removing catalytic converter

  1. Open the double clamping sleeves by undoing the hexagon nuts M8 (a/f 13) and moving them towards the catalytic converter. If necessary, pry the clamps apart and then move them. If there is corrosion, removing the exhaust pipes and clamps is made easier by heating. Double clamping sleeves must be replaced.
