There are 2 stainless steel exhaust manifold samples with shot blasted surface made by lost wax casting.
The exhaust manifold are usually made of high-quality 304 stainless steel. The material has excellent corrosion resistance, high-temperature resistance, and oxidation resistance, which can ensure the service life and performance stability of the exhaust manifold in harsh working environments.
The pipe diameter of the exhaust manifold is designed according to the customer's drawings. There are common structures like 4-1, 4-2-1, etc. The 4-1 structure is simple and has good exhaust gas convergence efficiency; the 4-2-1 structure can better adjust the exhaust gas pulse, improve the engine's torque and power performance in a specific speed range, and is widely used in modified engines.
Before sending them to customer getting approved, we inspect them carefully, check their key dimensions to ensure them qualified:
Then they are wrapped with 3 layers bubble foam to aviod scratching and bumping during shippment.
Fianlly put them into carton.
