DAMAGED EXHAUST SYSTEMS RISK YOUR SAFETY AND SANITY
If your exhaust is damaged (punctured, cracked, etc.), exhaust fumes such as carbon monoxide and carbon dioxide can seep into the cabin and irritate you and your passengers. The ever increasingly LOUD noise coming from the backend of your car, however, will just drive you crazy (your neighbors will know every time you start your car, you’ll be embarrassed by the noise in drive-thrus and at stop lights, and you’ll have to turn your radio up pretty loud to drown out the growing noise of your broken exhaust inside your vehicle). You’ll also draw the unwanted attention of law enforcement, resulting in citations.
If your exhaust needs repair, schedule an appointment with one of our local auto repair shops in Greenfield and Hales Corners! Reis Automotive offers services SO good and prices SO fair, YOU will feel guilty!
UNDERSTANDING YOUR CAR’S EXHAUST SYSTEM
Exhaust pipes are specifically designed to tightly conform to the underside of your vehicle, preventing bumps and scrapes as you drive along. Because these parts are so specific and vary greatly by vehicle, repairs can quickly become expensive. For this reason, Reis automotive offers free exhaust inspections.
Your exhaust system is designed to guide exhaust gases away from the controlled combustion inside your engine. Depending on the system, your exhaust system may be comprised of:
- cylinder head and exhaust manifold
- turbocharger to increase engine power
- catalytic converter to reduce air pollution
- muffler, also known as a silencer in some places, to reduce noise
Maintaining the optimum performance of your exhaust system is essential for fuel mileage, protecting the environment, and maintaining your safety.
Common Parts of Your Exhaust System Explained
Exhaust manifold: attaches to the cylinder head and gathers each cylinder’s exhaust into one pipe, most commonly made of cast iron.
Oxygen sensor: modern, fuel-injected cars employ up to four oxygen sensors, which are located in the exhaust line before and after the catalytic converter. These monitor fuel/oxygen trim levels going into the converter, then measure emissions that exit the exhaust manifold to optimize fuel economy.
Catalytic converter: converts harmful carbon monoxide and hydrocarbons to water vapor and carbon dioxide, found between the exhaust manifold and the muffler.
Muffler: keeps the engine and exhaust emissions quiet, the combustion process is a series of explosions that is very noisy.
Exhaust pipes: connects all of the above and conducts the exhaust away from the engine.
COMMON EXHAUST PROBLEMS
- Rust and corrosion, often caused by road salt, eats away at the muffler and exhaust pipes, creating holes that make the system loud. Water vapor that is collected in exhaust systems may not burn off on short trips, which will speed corrosion. In extreme cases, these can affect the drivability of a car.
- Catalytic convertor can become clogged. Symptoms include loss of power, heat coming from the floor of your car, or a sulfur smell.
- Road damage and debris can damage exhaust components. If your car bottoms out, you may break welds along the exhaust pipe lines, dramatically increasing noise.
