The exhaust system of your vehicle has the important job of converting harmful gases emitted from the engine into less harmful gases which are then emitted from your exhaust system. If your vehicle has an exhaust system, harmful gases could potentially be leaking into your cabin which is detrimental to you and your passenger's health. A exhaust system problem can also make you vehicle fail an emissions test and make your vehicle legally not able to drive. 

Some of the most common causes of exhaust system problems include: 

• Rust - rust can occur often when it comes to the muffler, pipes, and other components of the exhaust system. Roads that still use salt in the winter can speed up this process even more. Rust should be removed from parts if possible, and if not, super rusty parts should be replaced. 
   
• Bad Oxygen Sensor - a bad oxygen sensor can cause problems when it comes to making sure that the air-fuel mixture is correct for your emissions system. This can cause the catalytic converter to fail, which can be costly to replace. 
   
• Catalytic Converter - the catalytic converter can fail, which can be caused by a bad oxygen sensor, bad spark plugs, leaks, ignition problems and more. 
   
• Hitting Road Bumps or Accidents - any damage to your vehicle can cause loose parts to clog the muffler and effect other components within the fuel system. Be careful while driving and avoid driving fast over speed bumps. 
   
• Exhaust Leaks - leaks within the exhaust system can cause issues with certain parts and cause smoke to appear from your muffler.
