What are the effects of a leak in the exhaust manifold?

[HoldenLynn]

There are multiple effects of a leak in the exhaust manifold. Detailed explanation of the effects of a leak in the exhaust manifold: If the leak is in the front section, it will reduce exhaust backpressure, leading to a loss of engine power, difficulty in starting, and increased fuel consumption. Explanation of leaks in other parts of the exhaust system: If the leak is in the middle section, the water produced by the exhaust pipe will corrode it over time, eventually causing rust. Severe damage may lead to the exhaust pipe breaking. As for a leak in the rear section, it may only result in noise issues and will not reduce exhaust backpressure or cause engine power loss or starting difficulties.
