Like anything in the modern day car, it’s a little more complex than that.
Exhaust manifolds, oxygen censors, the catalytic converter and the muffler work in unison to create cleaner emissions while reducing engine noise and protecting you from harmful gasses. Without this system, driving wouldn’t be much fun.
The Exhaust System Helps Diagnose Car Problems
The exhaust system plays a helpful role in determining automotive issues. All you have to do is look at the color of the exhaust emitted from the tail pipe. The skilled technicians at Christian Brothers Automotive Omaha have laid out what each exhaust smoke color means, depending on if your car has a gasoline or diesel engine.
Vehicles with Gasoline Engines
