What is the temperature of vehicle exhaust at the muffler?

The temperature of vehicle exhaust at the muffler typically ranges from about 300°F to 500°F (150°C to 260°C), depending on the engine's operating conditions and load. This temperature can vary with factors such as the type of fuel used, engine design, and vehicle speed. As the exhaust travels through the system, it generally cools down before exiting the tailpipe.
