Catalytic converters are essential components of Toyota Tundra’s emission control system, converting harmful exhaust gases into less toxic or harmless forms. They can be found on all kinds of engines such as V8s, inline-fours, and rotary engines alike.

Today’s vehicles produce virtually zero harmful emissions due to advances in engine, electronics and converter technologies. Examples of these innovations include START-STOP, Hybrid drive systems and cylinder de-activation technologies.

These technological advances are advantageous, saving you money on fuel and increasing your vehicle’s mileage. Unfortunately, they’re not perfect and can be damaged due to misfires, too much fuel consumption, or physical trauma such as a rock hitting the unit.
