Red hot exhaust typically occurs due to excessive heat generated in the exhaust system, often caused by an overly rich air-fuel mixture, ignition timing issues, or a malfunctioning catalytic converter. When the engine burns fuel inefficiently, unburned fuel can ignite in the exhaust system, leading to high temperatures. Additionally, restricted airflow due to blockages can trap heat and elevate exhaust temperatures. This phenomenon can indicate underlying engine performance issues that should be addressed to prevent damage.
