Your vehicle’s exhaust is an integral part of the operating system. It stretches beyond just muffling sound before the fumes exit the car. In fact, it begins at the point where the manifold and engine cylinders connect. The fuel and air mixture are gathered into a single pipe to begin their journey out into the atmosphere.

The first stop is the oxygen sensor, where the air and fuel mixture is evaluated for proper emission levels before they’re sent on their way to the catalytic converter.
