The factory-installed exhaust system in your INFINITI G37 is there for a reason. Several, actually. It's responsible for removing the toxic byproducts produced when the engine consumes fuel, while allowing cleaner gases to escape harmlessly into the air. In addition, some components help to limit the noise produced during the process.

How Exhaust Systems Work

First, the pollutants pass through a catalytic converter. That's where metals like platinum, palladium, and rhodium capture the toxic molecules and then separate them into nitrogen and oxygen. The oxygen molecules are allowed to continue along the system, while the nitrogen molecules remain trapped. The process burns hydrocarbons and carbon monoxide, leaving behind little more than water vapors and carbon dioxide.

Next, the exhaust manifold gathers the gases and sends them to the exhaust pipe. At the same time, the resonator and muffler ensure ideal airflow and limit engine noise. Finally, the clean gases exit the tail pipe into the atmosphere.

How to Spot Issues With Your Exhaust System

Even the best exhaust system parts can begin to go bad. Signs of trouble include:

  • Poorer fuel economy
  • You detect the odor of rotten eggs in the air
  • You hear odd noises coming from your exhaust pipe
  • The "Check Engine" dash light comes on
  • Save Up to 30% on Genuine INFINITI Exhaust Parts
