Exhaust manifold

The exhaust manifold in an internal combustion engine collects and directs exhaust gases from the cylinders to the exhaust pipe. It also controls heat dissipation and can serve as a mounting point for the lambda sensor in modern vehicles.

The exhaust manifold is replaced due to corrosion, rust and cracking, which can cause leakage of exhaust gases. Wear from exposure to heat and pressure variations can also adversely affect engine performance. A damaged exhaust manifold can cause sounds of exhaust leaks and interfere with fuel tuning if it serves as a mounting point for the lambda sensor. It can also lead to increased emissions, making the vehicle non-compliant with emission standards and possible fines. Overall, replacing a damaged exhaust manifold improves engine performance, reduces noise pollution and ensures vehicle safety and reliability.
