Step 1: Lift the car

The first step in replacing the right catalytic converter is to lift your car using a hydraulic jack and secure it with jack stands. This will give you access to the underside of your car.

Step 2: Locate the right catalytic converter

The right catalytic converter is located on the passenger side of your car, between the engine and the muffler. Look for a large metal cylinder with pipes on either side.

Step 3: Remove the old catalytic converter

Using your ratchet set, remove the bolts that hold the old catalytic converter in place. Be careful not to damage the surrounding pipes and components.

Step 4: Install the new gasket

Place the new gasket on the flange where the old catalytic converter was attached. Make sure it's properly aligned and seated before proceeding.

Step 5: Install the new catalytic converter

Carefully attach the new catalytic converter to the pipes on either side. Use new bolts to secure it in place, and make sure it's snug but not too tight.

Step 6: Lower the car

Once the new catalytic converter is installed, carefully lower the car back to the ground using the hydraulic jack. Remove the jack stands and test your car to make sure everything is working correctly.
