How To Identify Catalytic Converter Failure

Like any car problem, there are always signs to indicate that something is wrong. Here are some signs and symptoms to look out for if you’re concerned about your exhaust system.

Leaking exhaust manifold

  • Cracked pipes: If you see a crack in one of your exhaust pipes, it’s almost guaranteed that it’s leaking. You can even shop for the VCM VE Commodore V8 OTR Intake kit to eliminate any kind of exhaust problems from your vehicle.

  • Increased noise when starting the engine or accelerating: While a noisier car can be a symptom of many different issues, when combined with some of the other issues on the list it can point to a leaking exhaust manifold.

  • Change in fumes: You may notice a stronger smell, more exhaust fumes, or even a change in the color of exhaust fumes. This is a huge red flag and should be investigated immediately. An increase in other exhaust fumes can also mean an increase in carbon monoxide, which is colorless, odorless, and incredibly dangerous.

Catalytic converter failure

  • Drop-in fuel economy: Notice that you’re stopping at the gas station more than you used to? That’s a clear sign that something is wrong with your vehicle.

  • Failure to accelerate when stepping on the gas: While every car accelerates differently, all cars should speed up when you step on the gas pedal. If not, something is amiss.

  • Check engine light comes on: While the check engine light can indicate any number of problems when combined with some of the above symptoms it’s an indication that you need to check the catalytic converter.
