Your exhaust system provides many functions to your car not only does it direct away the exhaust fumes it improves the performance and fuel consumption of the vehicle.
Not all exhaust systems look the same this can depend on many factors but they all work in a similar way. The exhaust ensures toxic gases are channeled away from the vehicle and passengers. These fumes are collected in the engine from the cylinder head by an exhaust manifold. First of all these gases are collected in the front pipe before travelling through a catalytic converter which removes carbon monoxide and hydrogen monoxide to be converted into inert gases.
Next, the gases go through a silencer which deflect the sound waves from the engine cancelling out the loud noise. If your car becomes very loud this could be due to the silencer becoming corroded and developing a hole.
Finally, the fumes will exit from the vehicle through the tail pipe and away from the vehicle. The whole exhaust system it held together and to the vehicle using sets of flanges,, hangers, gaskets and clamps.
