Why are exhaust baffles used?
Exhaust baffles are used primarily to reduce the loud noise generated by a vehicle's engine. Such loud noises are a nuisance and are characterized as noise pollution. Most countries worldwide have specific laws against such noise pollution. Thus, exhaust baffles prevent noise pollution and help motorists uphold the law.
How does exhaust gas work?
These exhaust gases are then pushed out of the vehicle via the exhaust system through the muffler and exhaust baffles. This process leads to the formation of additional pressure (back pressure) on the vehicle engine, leading to a reduction in engine horsepower output and torque and increasing strain on the engine.
Why does my exhaust baffle make a rattling sound?
With time, exhaust baffles may deteriorate due to wear and tear and exposure to exhaust gases and heat. This deterioration causes leaking, which can create an irritating rattling sound every time the vehicle is used. Since exhaust baffles cannot be repaired, they will have to be replaced entirely. This increases the costs associated with vehicle maintenance.
What is exhaust baffle?
