Explore the Exhaust Parts in Your Dodge Viper

There are many different exhaust parts in your Viper, and each piece is necessary to keep your exhaust system running smoothly. Not only does a high-performing exhaust system keep you safe, but also improves your fuel mileage and reduces emissions. 

How well do you know the exhaust system of your Dodge? Here’s a simple breakdown of all the main exhaust parts you will find in your Dodge Viper.

Exhaust manifold

The Exhaust Manifold is the exhaust part in your Dodge responsible for combining all your vehicle’s exhaust into one pipe. It connects to each cylinder on your engine and funnels those gases to the same place. After the exhaust manifold funnels all the exhaust into the same pipe, those gases begins the journey through the exhaust system.

The exhaust manifold deals with a tremendous amount of heat from the engine, which will wear on it over time. Since this exhaust part in your Viper deals with such hot and toxic gasses, cracks in the part could expose you to dangerous toxins. It will also reduce your engine’s performance.

This exhaust part is most often made out of cast iron, but can also be produced from aluminum, steel, or stainless steel. If something is wrong with your exhaust manifold, you may see the Check Engine light come on. Other signs include leaks, loud noises, and strange orders from the exhaust manifold.

Exhaust pipes

The exhaust pipes in your Dodge carry hot and toxic gases away from the driver, so they’re important parts for keeping you safe. There are a few different types of exhaust pipe that connect the various other pieces of your Dodge’s exhaust system.

Rust and corrosion are your worst enemies when it comes to the exhaust system. Moisture on the metal can eventually rust through and damage the pipes. If any of your exhaust pipes rust through and start dragging on the road, get them replaced as soon as you can!

High-quality Viper exhaust parts are less likely to rust through, but there are still steps you can take to reduce rusting. Keep the bottom of your car dry and avoid driving through deep puddles on rainy days.

We see a fair amount of rain where our dealership is located in Chicago, Illinois, along with snow in the winter. This creates a lot of opportunities to get the bottom of your Dodge wet and speed up the corrosion on your exhaust pipes. Driving for at least 15 minutes should warm up the pipes enough to vaporize the water and slow down the rusting.

In the winter, note that salt can speed up the rusting of your Viper’s exhaust parts. Wash the bottom of your car if you live in an area that salts the roads during winter.

Oxygen sensor

In order to make your Dodge as fuel-efficient as possible, you must have a functional oxygen sensor. This exhaust part in your Viper is responsible for measuring difference between the amount of oxygen in the exhaust gas and what’s in the air.

From there, the part’s internal computer can add or subtract fuel in order to create the right mixture. The right mixture of air and fuel will maximize your car’s fuel economy. If your oxygen sensor starts to wear out, your car may begin to run on fuel that is too rich or too lean, hurting your gas mileage.

Oxygen sensors do wear out over time, but they’re not too expensive to replace so it’s worth it when you’ll be able to get more miles out of a tank of gas. It’s typically recommended to replace your oxygen sensor every 60,000 miles.

Catalytic converter

The next exhaust part in your Viper is the catalytic converter, commonly referred to as just “cats” by those in the field. This part of your Viper’s exhaust system converts carbon monoxide and hydrocarbons into water vapor and carbon dioxide. Some catalytic converters will also reduce harmful nitrogen oxides.

Since this exhaust part gets rid of harmful toxins produced by your vehicle, it can be dangerous to go without one. The toxins are not only harmful, but also smelly and can make your Viper stink. Cars in the US are required by law to have a catalytic converter and you will need it to pass a smog test.

Fun fact: Catalytic Converters include precious metals such as platinum, palladium, rhodium, and gold. This makes it one of the most expensive exhaust parts for your Viper. Unfortunately, this also makes it a high target for thieves.

Luckily, the catalytic converter is a sturdy part and has an average life of around 100,000 miles, so you won’t have to replace it very often.


This is one of the more commonly-know exhaust parts on your Viper and other cars. By itself, the exhaust system can be very loud, so the muffler is responsible for reducing the noise level.

With acoustic soundproofing, mufflers are designed to trap the sound and muffle it. Many mufflers use a fiberglass layer for this.

Since the muffler does create some back pressure in the car, it does reduce some of the engine’s efficiency and power. However, the Dodge Viper has plenty of power with an OEM exhaust system, and the muffler is necessary for a smooth and quiet ride.

When your muffler fails, your car will run louder than before. You may also hear a rattling sound, which could signal that the muffler is loose or broken.

The Dodge Viper runs notoriously hot, so many car owners also invest in heat shields to reduce the stress on the exhaust system. If you make any repairs to the exhaust parts of your Viper yourself, make sure your car has plenty of time to cool before you touch it! The system will be very hot and could lead to serious burns.

There are other exhaust parts for your Viper, like gaskets and clamps, but these five parts make up the main components of your exhaust system.
