Hedman headers

Types of Hedman Headers

Hedman headers come in different types, making it easy to choose the right one for a vehicle. Below are some common types of Hedman headers:

• Hedman Long Tube Headers:

  Long tube headers offer a straightforward design that maximizes exhaust flow. These headers have long, straight tubes that channel exhaust gases from the engine to the collector. The extended length of the tubes enhances low-end torque and overall horsepower. Long tube headers are ideal for muscle cars, trucks, and street performance vehicles.

• Hedman Shorty Headers:

  Shorty headers are another type of Hedman headers. They are designed to replace the factory exhaust manifold and connect to the exhaust system at a closer point. While shorty headers do not offer the same level of performance gains as long tube headers, they provide a noticeable improvement over stock manifolds. They are often chosen for applications where space is limited or for vehicles that primarily focus on street driving.

• Hedman Mid-Length Headers:

  Mid-length headers combine features of both long tube and shorty headers. They are designed to provide a balance between low-end torque and high-end power delivery. Mid-length headers are a popular choice for many street performance applications, offering versatility and improved exhaust flow.

• Hedman Tri-Y Headers:

  Hedman Tri-Y headers feature a distinctive 3-into-2-into-1 design. This configuration contributes to smoother exhaust flow and better scavenging effects, resulting in improved torque and throttle response. Tri-Y headers are often preferred for racing and high-performance applications where every bit of power matters.

• Hedman Ceramic Coated Headers:

  Ceramic coated headers are designed for high-temperature durability and corrosion resistance. The ceramic coating not only extends the life of the headers but also helps maintain optimal exhaust gas temperature. This makes ceramic coated headers suitable for both street and track use.

Specification & Maintenance of Hedman Headers

Hedman header manufacturers give their products distinct identifiers that make it easy to tell one header from another. These identifiers are called part numbers, and they come in a combination of letters and numbers that represent certain specifications.

The following are some of the key specifications that part numbers will indicate:

• Type of header: As discussed earlier, headers come in different types. Hedman headers part numbers will indicate whether it is a long tube or short tube header.
• Material: The Hedman header part number will also indicate the material that has been used to make the header. For instance, it could be made from steel or stainless steel.
• Coating: Headers can be coated in different ways. Some of the common types of coatings include chrome and high-temperature paint. Each of the coatings has its benefits and applications.
• Flange thickness: Hedman headers have different flange thicknesses. The thickness of the flange will affect the durability of the header.
• Bolt hole diameter: This specification indicates the size of the bolt holes that are used to fasten the header to the engine block.
• Tube diameter: The diameter of the tubes on the headers determines the flow of exhaust gases. Different sizes are suitable for different types of vehicles.

While headers are generally durable, it is important to carry out regular maintenance checks to ensure they are in good condition. The following are some of the maintenance tips:

• Check for Rust and Corrosion: Hedman headers are made from metals that are prone to corrosion. Carry out regular inspections to check for signs of corrosion. If there are any signs of rust, replace the headers immediately.
• Check for Cracks and Leaks: Inspect the headers for any signs of cracks or leaks. A crack on the headers could lead to leaks, which can be dangerous. In case of any damages, replace the headers.
• Retighten Bolts: Over time, the bolts on the headers can loosen. Make a point to check that the bolts are tightly fastened, preferably on a monthly basis.
• Clean the Headers: When dirt and grime accumulate on the headers, it reduces their efficiency. Clean the headers regularly to remove any dirt.

How to choose Hedman headers

When choosing Hedman headers for resell, consider the type of vehicles the target customers use. The vehicle's make, model, and year of manufacture are essential, as headers designed for one vehicle may not fit another. It is also good to check the header material. Hedman headers are made from different materials. Each one has its benefits. For example, headers made from stainless steel are durable and resistant to corrosion. On the downside, they are more expensive than carbon steel headers.

Another material that is affordable and a good choice for Hedman headers is mild steel. Mild steel headers are suitable for everyday use and can last for many years with proper care. Hedman headers also come in different coating options. Choose headers with a coating that will appeal to the customers. Some of the coating options include chrome, black satin, and silver ceramic. Finally, consider the type of engine in the vehicle. Some headers are designed to increase power in small block engines, while others work best in big block engines.

How to diy and replace hedman headers

Header gaskets

• Remove old gaskets and clean the surface.
• Place the new gaskets into position.

Header bolts

• Insert the header bolts and hand-tighten.
• Use a wrench to tighten the bolts.

Collector gasket

• Remove the old collector gasket.
• Place the new collector gaskets between the flanges of the headers and the exhaust pipes.
• Use header bolts to secure the exhaust pipes to the headers.

Q&A

Q1: What material is best for headers?

A1: Hedman headers are made from different materials, each with its advantages. One can choose between cast iron, stainless steel, and mild steel. Stainless steel is the best material because it doesn't rust. It also lasts long and can handle the extreme heat from the engine. However, it is quite expensive. Cast iron is another good material for headers. It is affordable, but the hedman headers tend to rust. One may require frequent replacements when using cast iron headers. Mild steel is also affordable but will only last a few months when compared to the other two materials.

Q2: How long do headers last?

A2: Hedman headers can last anywhere between 5 to 10 years. The longevity of the headers depends on the material, maintenance, driving conditions, and weather. For example, stainless steel headers can last for a long time because they are rust-resistant. On the other hand, cast iron and mild steel can easily get damaged by rust when they are not maintained properly.

Q3: Why do headers crack?

A3: The headers can crack due to several reasons. One of them is thermal cycling, which is the constant heating and cooling of the headers. This usually happens when the driver accelerates or stops the vehicle suddenly. Another reason is physical impact where the headers get hit by a large object on the road. Poor installation and defective material can also cause the headers to crack.

Q4: Can a cracked header be repaired?

A4: Yes, a cracked header can be repaired. Users can weld the crack to seal it. However, manufacturers and experts recommend replacing the cracked header. This is because welded headers can reduce the performance of the vehicle.
