Removal the catalytic converter (Chevrolet Lanos T150)

We remove the catalytic converter when replacing it and when removing the exhaust manifold.

To avoid burns, it is recommended to start work after the exhaust system has cooled down.

We disconnect the flanges of the intermediate pipe and the catalytic converter and remove the sealing gasket (see Removal the intermediate pipe).
