Exhaust Tailpipe -

Exhaust Tailpipe

The exhaust tailpipe is the final component of your exhaust system that carries the exhaust fumes out of the rear of the vehicle where they are dispersed into the outside air. The exhaust gases are produced when the fuel and air mixture is burned by the engine cylinders.

From there, exhaust manifolds redirect the exhaust to the catalytic converter, where pollutants are filtered out. The filtered exhaust fumes enter the muffler where they are then finally passed through the exhaust tailpipe. Some vehicles may have dual tailpipes which sit side-by-side.

Signs of a bad exhaust tailpipe

Loud engine noises – Your exhaust tailpipe is also responsible for diverting noise away from your engine. If your tailpipe gets too worn, this noise may escape before it gets a chance to exit at the rear of the vehicle, causing you to hear the louder engine noises.
Rattling noise from underneath the vehicle – When your tailpipe detaches from your exhaust system, you will likely hear a rattling noise as a result. This can also occur as the result of too much rust on the tailpipe.
Vibrations – The exhaust system is suspended underneath your vehicle by a series of rubber hangers. When your exhaust tailpipe gets bad, it will throw your exhaust system off-balance and the different components may start to touch each other. This results in a vibration that is felt when driving.
Dragging noise – If your exhaust tailpipe gets detached, you will hear the continuous sound of it dragging across the road. When this happens, stop your vehicle immediately and check to see if your tailpipe is touching the ground. If it is, get your car to the mechanic right away.
Poor fuel economy – A rusted out or worn tailpipe will negatively impact your engine’s performance and can result in a drop in engine power and fuel economy.
Check engine light illuminates – Issues with your exhaust tailpipe can trigger the check engine light.
