High flow catalytic converter removes a percentage of damaging emissions which a car produces. The environmental regulations order emission reduction methods which every state should follow. Auto manufacturers include this kind of emission control equipment among new trucks and cars. But once operation exceeds the restrictions of the converter's capacity to operate appropriately, it becomes essential to replace it to preserve the same intensity of conversion during the time when the converter is new. If old high flow catalytic converters stay in use after its life expectancy, your car can fail emission control tests. It is simple to install a high flow catalytic converter along with some ordinary shop tools.
Step 1 - Elevate the Car
Check the car for fluid leaks once it is already elevated. Ensure that the high flow catalytic converter area is dry and free from fuels which may catch fire during the removal of the old converter. Mark the car’s exhaust piping three inches before and after the converter. Compare the distance to the new converter’s length then adjust for a proper connection between the exhaust piping and the new high flow converter.
Step 2 – Cut the Metals
Place the cutting torch tanks close to the work area so that the cutting head reaches the converter and then operate generously. Open the air and gas valves on top of every tank then clutch the igniter. Open its valves in good proportion along the cutting handle in order to turn the cutting flame to an intense and clear blue-colored gas flame which can cut out metals. Push the air injection tab just to make a cutting flame which cuts out an old converter easily and quickly. Cut all around the marks created along the exhaust pipes as well as outside of the converter’s outlet and inlet.
Step 3 - Grind the Exhaust Pipes
Grind the exposed part of exhaust pipes using an abrasive wheel and hand held grinder. Depending on the new high flow catalytic converter that has expanded pipe ends which slide over the exhaust pipes. The converter needs to be fastened using a stick welder. Prepare the exhaust pipes’ end and the converter for welding work. The welded high flow catalytic converter is expected with high performance all through the car’s life. Take your time to follow this step before welding to get an enhanced result.
Step 4 – Weld and Install
Connect the exhaust pipe to the ground which will be welded then hold down the new high flow catalytic converter in place, border to border along with the existing exhaust piping. Use welding glasses for eye protection and contact the stick towards the joint of its two parts. When the connection is completed, hold it in place for 3-5 seconds, and then pull it away. Repeat this procedure once again on the piping’s opposite side then along the converter’s other end. This tack weld can keep the pieces together until you complete the welding and instillation work. Finally, complete the converter welding surrounding both the outlet and inlet pipes of the high flow catalytic converter which is now free from any leaks.
