WHAT IS AN EXHAUST SYSTEM?

Vital for fuel economy and the environment, your vehicle’s exhaust system carries away harmful gases that are created during the combustion process. The exhaust system not only keeps dangerous gases like carbon monoxide, nitrogen oxides and hydrocarbons from entering the cabin but it also "cleans up" the gases before they are released into the environment. Here are the components of an exhaust system:

  1. Manifold/Manifold Converters
  2. Flex Pipes
  3. Catalytic Converters
  4. Oxygen (O2) Sensor Ports
  5. Isolators/Gaskets/Clamps
  6. Resonator Assemblies/Pipe Accessories
  7. Mufflers/Muffler Assemblies
