20 Best Exhaust For Subaru Rumble (2023 Updated)

The Subaru rumble is a noise that some Subaru vehicles make when idling. It is caused by the engine’s exhaust system, and is most noticeable when the engine is cold. The rumble is caused by the exhaust system’s design, which allows some of the exhaust gases to escape through the engine’s intake system.

This causes the engine to run richer, which creates the rumble. The rumble is not harmful to the engine, and is actually quite normal.
