As your auto engine burns fuel, it produces gases. The exhaust system moves these fumes away from the engine, preventing them from wearing away at the component or presenting health hazards by entering the cabin. Problems with exhaust pipes and mufflers require attention from a professional auto repair shop to rule out the possibility of serious vehicle damage and safety risks. Here’s how to tell when there’s trouble with your system. 

4 Common Auto Exhaust Problems

1. Corrosion

Exhaust pipes and mufflers are made from metal. Due to exposure to salt and moisture, the metal oxidizes over time and can become corroded, making it vulnerable to noxious fume leaks.

When this happens, you’ll likely notice flaky copper spots on the exhaust pipe. An auto repair shop can remove the rusted pipe segments and weld stainless steel in its place.

2. Blue or Black Smoke

When exhaust exits your muffler, it should have a translucent white color. Blue smoke indicates burning oil caused by deteriorated valves, cylinder walls, or piston rings. 

Black smoke occurs when the ratio of fuel to oil is out of balance due to a faulty oxygen sensor. A mechanic can replace any of these components to keep fuel burning normally and safely. 

3. Loose or Missing Hangers

Hangers prevent the exhaust system pipes from shifting and becoming dented when you roll over bumps or rough terrain. When they loosen or fall off, the pipes will move around, potentially denting or cracking. An auto repair shop can install new hangers to prevent damage and noxious gas leaks. 

4. Loud Engine

Exhaust systems serve the secondary purpose of muffling engine noise. However, leaks in the system, such as along pipe joints, result in loud rumbling sounds. A mechanic can patch pipe leaks and prevent toxic fumes from harming people and the environment.
