Exhaust and muffler are both components of a vehicle's exhaust system, but they serve different purposes.
Exhaust: The exhaust system is responsible for carrying the exhaust gases produced by the engine out of the vehicle. It starts from the engine manifold and includes various pipes, catalytic converters, and other components that help control emissions. The primary function of the exhaust system is to direct the exhaust gases away from the engine and reduce noise.
The muffler is a specific component within the exhaust system, The purpose of a muffler is to reduce the noise produced by the exhaust gases of an internal combustion engine. It contains chambers and bafflesa, it is device that is installed in the exhaust system of a vehicle to muffle or dampen the sound waves created by the engine's combustion process. Additionally, mufflers also help in improving the overall engine performance by controlling the backpressure in the exhaust system, minimize the noise generated by the engine, making the vehicle quieter.
In summary, the exhaust system is the entire system responsible for routing exhaust gases out of the vehicle, while the muffler is a specific component within the exhaust system that reduces the noise produced by the engine.
