Question 8178
When the exhaust pipe is damaged, what happens?
- The noise decreases.
- The vehicle uses more fuel.
- The vehicle makes more noise.
Show answer and explanation
Correct answer: The vehicle makes more noise.
If the exhaust pipe breaks or develops a hole, the muffler no longer works properly and the vehicle makes more noise than normal, like the passenger car in the image with its exhaust hanging down. Have it repaired as soon as possible.
