1. Material selection
The material of the tail throat directly affects its appearance, corrosion resistance, and durability. The common tail throat materials on the market currently include stainless steel and galvanized

Stainless steel: Stainless steel material has excellent corrosion resistance and high temperature resistance, and is not easy to deform or leave fingerprints. The tailpipes modified by high-end car brands are often made of stainless steel materials, such as 304 stainless steel. Due to its anti rust, anti-oxidation, and scratch resistant properties, it can maintain its appearance and performance for a long time.

Galvanizing: Galvanized tail throat is a process of coating a layer of zinc film on the metal surface to improve corrosion resistance. However, over time, the zinc film may peel off, thereby affecting its anti-corrosion effect.

2. Production process
The production process of tail throat is complex and diverse, including various processing and surface treatment techniques to ensure product quality and aesthetics:

Metal processing:

Wire drawing process: a metal processing technique that uses external force to force metal through a mold to obtain the desired cross-sectional area, shape, and size. Porsche's brushed tail throat adopts this process, making the product look exquisite and gorgeous, with a special metallic texture.
Welding process: The internal structural components of the tail throat are usually connected to the outer shell using welding technology. The internal structural components of the stainless steel tail throat may be welded using spot welding technology, while the shell connection may be welded using argon arc welding technology. These welding processes can ensure high welding accuracy, high weld strength, and beautiful welding.


Surface treatment:

Vacuum electroplating: After precision polishing on the surface of the tail throat, vacuum electroplating technology is used to improve the glossiness and adhesion of the product. The electroplating layer can further enhance the corrosion resistance, hardness, and wear resistance of the tail throat.
High temperature black paint treatment: Some internal structural components of the tail throat will be sprayed with high-temperature black paint to enhance overall aesthetics and heat resistance.
Oil film drawing: After surface processing, the material surface will form extremely fine straight lines, giving the tail throat a unique metallic texture and delicate hand feel.

3. Style and Design
There are various styles of tail throats to meet the needs of different consumers. Tail throat styles can be divided into brushed silver, electroplated silver, and electroplated black styles. Different styles of tailpipes may have differences in craftsmanship, but they are all designed to enhance the appearance and performance of the vehicle.

4. Installation and use
The installation of the tail throat is relatively simple and can usually be quickly completed through replacement installation. After installation, the tailpipe can protect the tail end of the exhaust pipe from corrosion and damage, while also serving as a decoration and boost turbulence. However, it should be noted that modifying the tailpipe should comply with local laws, regulations, and rules to ensure driving safety and legality.
In summary, the manufacturing process of the tail throat involves multiple stages such as material selection, metal processing, surface treatment, and style design. Through precise manufacturing techniques and high-quality material selection, high-performance and aesthetically pleasing tail throat products can be produced.
