Too Afraid to Ask

An exhaust leak is like a hole in the car’s breathing tube. Hot gases escape, making the engine less efficient and sometimes louder or smelling bad.

Technical Definition

An exhaust leak occurs when a hole, crack, or loose connection in the exhaust system allows gases to escape before reaching the muffler. This can reduce engine efficiency, increase noise, and expose occupants to harmful gases.
