Exhaust Systems for Jeep Wrangler

Without the exhaust system, your Jeep Wrangler can become a dangerous place to be. Becoming aware of the system and how it works will provide you with the knowledge necessary to properly operate your Jeep. Maintaining this system is essential for safe use of your vehicle.

What is an exhaust system?

Overall, the exhaust setup is designed to guide toxic gases that are formed in the engine to the outside of the vehicle. Those gases are harmful to humans and the environment. Different parts come together and assist in this process.

  • Exhaust manifold: Made of steel, aluminum, stainless steel, or cast iron, this manifold attaches to the cylinder heads and combines each cylinder's exhaust into one pipe.
  • Oxygen sensor: This tool monitors the oxygen level in the exhaust.
  • Catalytic converter: This part converts harmful hydrocarbons and carbon monoxide to water vapor and carbon dioxide while reducing harmful nitrogen oxides.
  • Muffler: This piece absorbs the sounds of combustion and quiets the exhaust system noises.
  • Exhaust pipe: Made of steel, stainless steel, or aluminized steel, this tubing carries the exhaust throughout the system to finally exit the tailpipe.
What are signs of exhaust system problems?

If you suspect a problem with any part of your Jeep's exhaust system, have it checked immediately to prevent serious harm to anyone riding in the vehicle through contact with toxic fumes Some signs are listed below:

  • Check engine light: While this is a broad warning indicator, it could mean an issue related to the exhaust.
  • Gas smells: There might be a leak somewhere in the system if you can smell gases inside the vehicle.
  • Noisy engine or tailpipe: There might be a leak or hole in the tubing or other parts of the process if the exhaust sounds louder than normal.
  • Loss of power or sulfur smell: These occurrences can indicate a clogged catalytic converter or issues with other parts.
  • Decreased fuel mileage: There might be a problem with your oxygen sensor's accuracy that causes your fuel usage to increase.
  • Hanging exhaust pipe: This needs to be repaired or replaced if it is visibly hanging from its attachments to prevent further damage or loss.
How long should a Jeep Wrangler's exhaust system last?

There is no average expectancy on the entire system as it is made up of separate parts. Corrosion and rust are major culprits of exhaust system damage, but their effect on its parts can vary depending on the frequency of rain and road salt that the Jeep is exposed to. Contact with rocks and speed bumps can also damage the metals that are exposed underneath.
