Exhaust diffusers are pieces of equipment installed into a vehicle's exhaust pipe. The diffusers dilute the exhaust gas that comes from the vehicle's engine and accelerates the gas' diffusion process, making it less of a health risk for the vehicle's operator and those nearby the vehicle.
Exhaust diffusers work by forcing a vehicle's exhaust gas to pass through a series of pipes, deflectors and diffuser plates in order to introduce more air into the gas mixture before fully expelling it from the vehicle.
Exhaust diffusers come in many different varieties. Some are specifically designed for small vehicles, while others are designed for large industrial vehicles. Some exhaust diffusers are designed for high-performance vehicles, such as race cars.
Before deciding on an exhaust diffuser, an individual must carefully analyze the benefits and drawbacks of acquiring a diffuser, as they can be expensive and difficult to install.
