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

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.
I've been driving for decades and have encountered exhaust manifold leaks several times. The leaks make the engine sound louder, especially when accelerating, it roars like a tractor, which is really annoying. More importantly, there's a noticeable drop in power, making it particularly difficult when climbing hills or overtaking, and fuel consumption shoots up, costing a lot more in gas each month. If left unrepaired for a long time, the leaking hot exhaust can burn surrounding wiring and even damage the catalytic converter or sensors, leading to much more expensive repairs. My advice is to get it checked at a repair shop as soon as you notice unusual noises or a lack of power—small repairs can prevent big problems.
