How to Punch Holes in Catalytic Converter

The catalytic converter is part of the exhaust system of an automobile and is designed to reduce pollution in the cars emissions. It oxides carbon monoxide and other pollutants into carbon dioxide and water by using a platinum-iridium catalyst. Sometimes the catalytic converter can become clogged with deposits and this can result in the engine not running properly. Puncturing the converter can solve this problem and allow the trapped gases a means of escape.

Instructions

1

Lift the car up on a jack so that you safely look under it to find the catalytic converter. Make sure the car is secure and that vibrations or small impacts will not affect the jack.

2

Locate the converter. It will normally be towards the back of the exhaust system near the muffler. Look for a cylinder-shaped casing with a pipe running in and out of it at both ends.

3

Determine if the converter is welded on to the exhaust of clamped. If it is clamped, remove the clamps and slide the converter off. If it is welded, saw through the piping on both ends of the converter to remove it.

4

Stand the converter on its end and hold the chisel tip in the piping against the end of the converter.

5

Use the hammer to hit the end of the chisel and force it through the catalytic converter. Do this on both ends. Be careful to not hit your hand with the hammer when you punch in the holes.

6

Re-attach the converter by clamping it back into place on the piping under the car.
