How to Check if a Car Has a Catalytic Converter?

The safest method is to take the car to a reliable repair shop and use a lift to check if the catalytic converter is still present underneath the chassis. Additionally, if the vehicle lacks a catalytic converter, the exhaust sound will be noticeably louder, and the exhaust gases will emit a very unpleasant odor. Below is some information about catalytic converters: Composition Elements: The catalytic converter contains metals such as platinum, rhodium, and palladium. Element Functions: Platinum, rhodium, and palladium effectively catalyze nitrogen oxides and particulate matter in the exhaust gases. Vehicles equipped with catalytic converters will not produce strong-smelling exhaust. Of course, a strong gasoline odor during cold starts is a normal phenomenon.

I had an experience when repairing my car before. The most direct way to check if a car has a catalytic converter is to lift the car and inspect the undercarriage. The catalytic converter is usually installed in the middle section of the exhaust pipe, shaped like a small box with a heat shield on the outside, making it easily recognizable. If you can reach the undercarriage, follow the exhaust pipe and feel for this hard component—if it's there, the converter is still intact. If you can't see it or feel an empty space, it might have been stolen or the old car might not have had one installed in the first place. This issue is quite common, especially in some used cars, because thieves specifically target them to sell for money. Before checking, make sure the car is safely parked with the handbrake engaged to avoid injury. I noticed that when the catalytic converter is missing, the car's exhaust smells particularly pungent, and the engine noise becomes louder while driving. Get it fixed immediately to avoid fines or air pollution.

As an average car owner, I find checking the catalytic converter isn't difficult. Just look at the tailpipe end from outside the vehicle. Normally, cars with catalytic converters have a honeycomb-like internal structure inside the exhaust pipe. You can try shining your phone's flashlight inside for a quick peek - you should see small grid patterns. If it's missing, the pipe will appear completely hollow. Also listen to the engine sound at startup: with a catalytic converter, the exhaust note will be smooth and deep; without it, the sound becomes noticeably buzzing and accompanied by vibrations. My car had this exact issue ten years ago, and later inspection revealed it had been stolen - cost me money to replace. Monitoring exhaust smoke color during regular use is also helpful: black or blue smoke indicates potential catalytic converter problems. I recommend checking it every few months - proper maintenance brings peace of mind.

Simply put, check the vehicle's production year to determine if it has a catalytic converter. Most countries have required new cars to be equipped with them since the 1980s, so checking the vehicle's nameplate or VIN code will tell you. For example, in China, cars produced after 2000 are generally equipped with one. Ask a car-savvy friend to help you locate the nameplate label under the hood, note the manufacturing date and model, then look it up online. Vintage cars might not have one, like my neighbor's old Liberation truck which lacks it. The inspection is quick—don't skip it. Without a catalytic converter, you won't pass the annual inspection, so watch out for fines.
