Evo headers

Types of Evo Headers

Evo headers are important components of an exhaust system. They help to improve the car's performance by increasing the exhaust flow. The headers replace the stock cast-iron exhaust manifold. There are different types of headers. Below are some common types of Evo headers.

• Stainless Steel Headers:

  Stainless steel headers are very popular among car enthusiasts. This is because they help to improve the vehicle's performance. They also have a long lifespan. Long-lasting headers mean less hassle and fewer costs for drivers. These headers are made from different grades of stainless steel. For instance, they can be made from 304, 321, or 409 stainless steel. 304 stainless steel headers resist corrosion. This makes them suitable for high-performance cars that use high-temperature exhausts. On the other hand, 321 stainless steel headers are great for general-purpose headers. They have good corrosion resistance and can withstand high temperatures. Lastly, 409 stainless steel headers are affordable. However, they have lower corrosion resistance compared to the other two types of headers.

• Cast Iron Headers:

  These headers have a simple design. They are cheaper compared to other types of headers. This makes them affordable for many drivers. Cast iron headers are very durable. They can last for many years with little wear and tear. This is because cast iron is a very strong material. However, these headers are heavy. Also, they do not transfer heat quickly. This makes them unsuitable for high-performance cars.

• Ceramic-Metallic Headers:

  These headers are made of steel. They are coated with a ceramic-metallic material. This coating helps to improve the header's performance. It also increases the header's lifespan. Ceramic-metallic headers can withstand high temperatures. They also reduce the heat transfer to the car's engine.

• Aluminized Steel Headers:

  Aluminized steel headers are made of steel. They are coated with aluminum. This aluminum coating protects the headers from rust. Aluminized steel headers also have good weldability. This means they can be easily welded to other parts of the exhaust system.

• Titanium Headers:

  These headers are made of titanium. This makes them very light and resistant to high temperatures. However, titanium headers are more expensive than other types of headers.

Specification and Maintenance of Evo Headers

Below are the specifications of the Evo headers.

• Material

  The headers are made with different materials, such as steel and cast iron. Steel headers are very durable. They do not rust, corrode, or break easily. On the other hand, cast iron headers are very strong and can withstand high heat. They do not warp easily. However, they are heavier than steel headers.

• Coating

  Some Evo headers have a coating on the surface. This coating protects the headers from damage and rust. It also makes them last longer. The coating can be made of chromium or nickel. Some headers are coated with a ceramic coating. This coating is very smooth and can withstand high temperatures. It is also available in different colors.

• Number of tubes

  The Evo headers have different numbers of tubes. Each tube connects to the exhaust pipe of each cylinder in the engine. The tubes then combine and connect to the exhaust system. The number of tubes in the headers ranges from 4 to 8.

• Style

  There are different styles of Evo headers. For example, some headers have a standard style, while others have a racing style. Racing headers are designed to improve the speed and performance of a vehicle. They are suitable for cars that race. The headers also make the car sound loud and aggressive.

• Size

  The headers are made in different sizes. The size of the header affects the performance of the vehicle. Larger headers improve the performance of the car. The diameter of the tube of the Evo headers ranges from 1.5 inches to 2.5 inches or more.

Below are some maintenance tips for Evo headers.

• Regular inspection

  The header should be checked regularly. The inspection helps to find any damage, crack, or rust on the header. If any issue is found, it should be fixed immediately. This prevents the problems from getting worse.

• Cleanliness

  The headers should be kept clean. Dirt and dust should be removed from the surface regularly. A smooth and clean cloth can be used to wipe the surface of the headers. The inside of the header can be cleaned with a header cleaning solution. This prevents carbon buildup from damaging the headers.

• Proper installation

  The headers should be installed properly. They should be fitted tightly and securely. Loose headers can cause leaks. The bolts and nuts should be checked regularly to make sure they are tightly fitted.

• Heat management

  The headers can get very hot when the car is being driven. They emit a lot of heat. Therefore, they should be kept away from materials that can catch fire easily. For proper heat management, the headers come with heat shields that protect the headers from high heat.

How to Choose Evo Headers

Choosing the right evo headers for a business can be a complex task, as headers come in different types and are designed to meet various needs. Here are some essential factors to consider when choosing an header for resale:

Firstly, consider the type of headers to choose from. There are several types of headers, including:

• Long tube headers: These headers have long, smooth pipes that allow for better exhaust flow, making them ideal for racing and high-performance street cars.
• Shorty headers: These headers feature a compact design that allows for easy installation. However, they do not provide better performance like long tube headers.
• Tri-Y headers: These headers combine the features of long and shorty headers. They are designed to improve torque.
• Stainless steel headers: These headers resist corrosion, making them a good choice for a long-lasting exhaust header.

Secondly, consider the material used to make the header. Common materials include steel, stainless steel, and cast iron. Each material has its advantages and disadvantages in terms of durability, resistance to corrosion, and heat resistance.

Another important factor to consider is the size of the headers. Choose a size that will fit the target customers' car model without causing any damage. When choosing the size, consider theDiameter of the header pipes: Larger pipes can increase power but may reduce low-end torque. The pipe length: Longer pipes can improve high-end power but may reduce low-end torque.

Additionally, check if the header is easy to install. Some headers come with installation kits that include all the necessary components for quick and easy installation.

How to DIY and Replace of Evo Headers

Replacing headers on a car can be a challenging task, but with the right tools and mechanical knowledge, it can be done. Before starting, make sure to check and comply with any emissions regulations that apply to the specific vehicle. Here's a general guide on how to replace headers:

Tools and materials needed:

• Socket set and wrenches
• Torque wrench
• Ratchet extensions
• New headers (e.g., stainless steel or ceramic-coated headers)
• Header gaskets
• Bolts and nuts (if not included with new headers)
• O2 sensor socket (for headers with integrated O2 sensor bungs)
