Exhaust manifold

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

The exhaust manifold is replaced due to corrosion, rust and cracking, which can cause exhaust gas leakage. Wear from heat exposure and pressure variations can also negatively affect engine performance. A damaged exhaust manifold can cause exhaust leak noises and disrupt fuel tuning if it serves as the mounting point for the lambda sensor. It can also lead to increased emissions, causing the vehicle to fail to meet emissions standards and potentially incur fines. In general, replacing a damaged exhaust manifold improves engine performance, reduces noise pollution and ensures vehicle safety and reliability.
