1. The role of exhaust manifold

Exhaust manifolds are essential in automobiles. Its main function is to reduce exhaust resistance as much as possible and avoid interference between cylinders. It is connected to the cylinder block of the engine, and the exhaust gas of each cylinder is collected and guided into the exhaust manifold through a branch pipe. When the exhaust is too concentrated, the cylinders will interfere with each other, that is, when one cylinder is exhausting, it happens to encounter the exhaust gas that is not discharged by the other cylinders, which will increase the exhaust resistance and reduce the output power of the engine.

Therefore, try to separate the exhaust of each cylinder, one for each cylinder, or one for two cylinders, and each branch is as long as possible and formed independently to reduce the mutual influence of gases in different pipelines.

2. The hazards of exhaust manifold after long-term use

However, because the exhaust manifold works in a high temperature environment for a long time, the oxidation rate is very fast and the rust is serious, which will not only reduce the exhaust efficiency, but also cause the engine power to drop. At the same time, rust will also affect the appearance of the car.

So replacing a new exhaust manifold will be of great help to your car. Especially for car modification and upgrade or racing, this is a very urgent need.

3. Reasons for choosing Refone exhaust manifold

(1) High product quality: An independent factory workshop specializes in exhaust manifold manufacturing, and has a professional and strict quality system to ensure high product quality.

(2) Accept customization: The exhaust manifold can be customized according to customer needs or samples, including materials, and the customized quantity can be arranged for production, only 20-30 pieces.

(3) Abundant supporting products: turbochargers and wastegates can be recommended according to the needs of exhaust manifolds to help customers upgrade.

(4) Price concessions: EXW prices, products have price advantages, and better help you open the market.
