Your exhaust is designed with a series of chambers and pipes that start with the engine and end at the vehicle's tailpipe. Most vehicles operate with one exhaust system, but eight-cylinder engines may have two different exhaust systems for the right and left cylinders. It is necessary for your exhaust system to run efficiently. The standard exhaust has five main parts.
1. Manifold The manifold is attached to the engine's cylinder head and vents the gasses from the chambers of the cylinder into one pipe and through the exhaust.
2. Oxygen Sensor The oxygen sensor sends the readings to the computer, which then regulates how much fuel is needed while providing the best fuel efficiency.
3. Pipes The pipes distribute the engine's exhaust beginning at the manifold and releasing it through the tail pipe.
4. Catalytic Converter The catalytic converter is in the exhaust system, and its primary purpose is to produce safer emissions.
5. Muffler Loud sounds are created by the combustion of air and fuel. The gasses, emissions and sound travel through the exhaust system to the muffler that is connected to the tailpipe. The muffler quiets these loud sounds.
The supportive parts in your Durango's exhaust system are often overlooked until they demand attention. Because the exhaust gaskets, seals, hangers and clamps are hidden out of sight, they are often corroded, worn and ready to be replaced long before they get the attention they need. When the pipes or the muffler are replaced, the corroded support pieces are usually placed back into position and are expected to hold the updated system without any issues. These parts may especially be corroded beyond the point of reusability if you live in the San Fransico Bay Area. The salty air and moisture from the morning dew mix in the early morning hours, which causes corrosion under the vehicle on the nuts and bolts and hangers in the exhaust system.
The most inexpensive parts in the exhaust system are responsible for properly attaching the expensive components to the vehicle, and spending some money to replace them when you are doing repairs on your exhaust will save you some unneeded maintenance in the future. A few extra dollars in parts could save you time and money in the future.
Professional technicians and mechanics advice that the exhaust system gaskets, clamps and seals are not designed to be replaced and used again after they've been removed. They aren't able to hold their shape and perform a second time efficiently.
Examine the exhaust and take note of the clamps and hanger pieces. Even if they aren't corroded, the exhaust's built-in nut and bolt threads are often too weak to maintain the needed bolt tightness adequately. Loose bolts, nuts and clamps may result in leaks, rattles, vibrations and noises in the exhaust.
Many of the exhaust system parts that are sold at MoparBayArea.com are vehicle-specific and are built to fit your model correctly. OEM parts are made to the exact specifications of the original factory installed parts. Each is a perfect match in dimensions and thickness. Universal fit components, on the other hand, are not factory made duplicates. They are designed similarly to the original but not exactly.
Exhaust System Hangers Your exhaust system hangers may need to be replaced if you hear a scraping sound as you pass over a dip in the road or when you turn into the entrance of a steep driveway. Part of the exhaust may be hanging too low because the hanger pieces have broken. Exhaust hangers are designed blocks, bands, metal hooks or brackets.
If you hear the exhaust drag, look along the length of the exhaust system under the vehicle. You may see a snapped metal hanger with half still attached to the vehicle and the other half separately connected to the muffler. The hook could be gone entirely, and the muffler system will be very low in an area that it should be supported. Replacing the exhaust hanger is an easy, uncomplicated process. The OEM, factory-manufactured exhaust suspension kit will include the correct replacement hanger with the nuts, bolts, washers and rubber insulators that are needed for installation.

Exhaust Manifold Gaskets The exhaust manifold gasket is specially shaped to form a seal between the exhaust ports and manifold. The gasket joins several pipes into one system. A faulty manifold gasket will permit exhaust gasses to leak from the engine and into unintended areas. An odd exhaust smell will occur under the hood, and a severe leak may also produce a hissing or tapping sound within the engine. This noise will be loudest during acceleration. Nearby plastic or wiring components may also melt or overheat during a severe leak and will produce a distinct burning smell.
Exhaust Pipe Gaskets Gasket seals create an airtight, secure seal between the sections of exhaust pipe. They vary in design depending on the vehicle and may be ring-shaped or flat. The exhaust pipe gaskets withstand intense heat and vibration and may need to be replaced due to wear. They should also be replaced when sections of pipe or the muffler are replaced.
Mopar offers the parts needed for your exhaust. Enter your VIN or the year and model of your vehicle to access the exact parts needed, including the nuts, bolts, bits, stud pieces and washers that should be replaced when you work on your exhaust.
New exhaust hangers, gaskets and components will keep your exhaust operating at its best. Change these parts when you see corrosion, hear the tailpipe dragging and when you change the main elements in the exhaust. When you replace these parts on their own or along with a complete exhaust system, your vehicle will sound better and will run smoother.
