Excessive Engine Roaring
There’s no way to miss how much louder your engine will be if you no longer have a catalytic converter. The engine will roar loudly and excessively.
Check Engine Illumination
The dashboard warning light activates because sensors detect malfunctions in the exhaust system that the engine control unit cannot resolve.
Acceleration That Jerks
C&C Automotive advises against driving a vehicle missing its catalytic converter, recommending towing instead. If operated, the automobile will experience jerky, lunging acceleration.
Sputtering at Slow Speeds
The engine performs normally at highway speeds but sputters when operating at lower velocities.
Exhaust Odors / Illness
The exhaust manifold no longer has the catalytic converter in which to push the exhaust. Consequently, the exhaust is released into the environment and can make its way to the inside of your vehicle. This situation poses health risks to occupants, making professional towing and replacement essential.
