What are the effects of a slight exhaust pipe leak?

[MacIsabela]

The main effects of a slight exhaust pipe leak are as follows: 1. It can affect the car's power and increase fuel consumption. The impact is more significant on turbocharged cars and relatively minor on naturally aspirated cars. 2. It can amplify the car's noise. Additional details: The impact of an exhaust pipe leak also depends on the location of the leak: 1. If the leak is in the front section, it can reduce exhaust backpressure, leading to weaker engine performance, difficulty in starting, and increased fuel consumption. 2. If the leak is in the middle section, the water produced by the exhaust pipe can corrode it over time, eventually causing rust. 3. If the leak is in the tail section, it has no effect on the car.
