Based on BMW's formula race cars of the late 1970's, the BMW M3 comes in a several body styles, including sedans, coupes and roadsters. People tend not to think much about the BMW M3 catalytic converter, yet when it comes to the environment, it's one of the vehicle's most important components. The BMW M3 catalytic converter is actually a simple mechanism.

Its purpose is to reduce emissions produced by an internal combustion engine. By treating the exhaust before it exits via the tailpipe, the BMW M3 catalytic converter removes most of the carbon monoxide, hydrocarbons and nitrous oxide gases that result when gasoline is burned.

Sometimes, the BMW M3 catalytic converter will become clogged with debris that blocks the flow of exhaust gas. This can affect your car's performance adversely.

Checking the performance of your catalytic converter is easy; remove the old oxygen sensor and exhaust pipe, the rev the engine to 4000 RPM. If you hear a whistling sound, the device is definitely clogged. If your fuel mixture is too "rich" - that is, contains too much fuel - the excess may burn in the catalytic converter, generating tremendous heat, melting the internal components. In any event, if your BMW M3 is emitting foul-smelling exhaust, and/or lacks its usual "pep," the solution may very well lie in a new BMW M3 catalytic converter.
