Catalytic converters are an essential part of your car’s exhaust system. They help to reduce harmful emissions and improve the overall performance of your vehicle.

Unfortunately, catalytic converters are also a popular target for thieves, who can sell them for a high price.

If you want to protect your catalytic converter, you may want to consider installing a catalytic converter lock.

Step 1: Cut the Steel Rod

  • Measure the diameter of your catalytic converter accurately.
  • Cut a steel rod to fit snugly around the converter.
  • Ensure the rod is long enough to extend at least 6 inches on either side of the converter.

Step 2: Weld the Steel Plate to the Steel Rod

  • Take the steel plate and weld it to the end of the steel rod.
  • The plate should be large enough to cover the entire end of the rod and provide a surface for welding.

Step 3: Grind the Steel Plate to Fit the Exhaust Pipe

  • Use a grinding tool to shape the steel plate to fit snugly around the exhaust pipe.
  • The plate should fit tightly enough to prevent the rod from moving but still be able to rotate around the converter.

Step 4: Install the Lock

  • Slide the steel rod around the catalytic converter, ensuring that the plate is resting against the exhaust pipe.
  • Use the welding machine to attach the rod to the pipe, securing the lock in place.

Step 5: Test the Lock
