Miata header

Types of Miata Headers

A Miata header is a part of a car's exhaust system. It is also known as a exhaust manifold. The Miata header takes the exhaust gases from the engine and sends them to the exhaust pipes. This way, the exhaust gases can leave the engine. The headers work to reduce the emissions from the vehicle and also help to improve the performance of the car.

There are different types of Miata headers that are suitable for various kinds of Mazda cars.

• Stainless steel headers: Stainless steel headers for Miata are high-performance headers made of stainless steel. The stainless steel material is very durable and resistant to corrosion. These headers also improve the exhaust flow due to their smooth pipes. They are able to increase the power of the engine. Stainless steel headers can also handle high temperatures without getting damaged.
• Cast iron headers: Cast iron headers for Miata are known to be very durable and can handle high levels of heat. They also have a strong and robust design, which means that they can last for a long time without getting damaged. The cast iron headers are also less noisy compared to other types of headers. This is because they have a strong ability to muffle the sounds that come from the exhaust.
• 4-1 headers: This type of Miata header has a design that is quite similar to the 4-2-1 headers. They have 4 pipes that merge into 1 collector. The 4-1 headers are known to improve the high RPM power of the vehicle.
• Staggered 4-2-1 Miata headers: Staggered 4-2-1 Miata headers are designed to improve the low-end torque and mid-range power of the engine. This is achieved through its staggered design and tuned pipe lengths. The exhaust ports of the headers are arranged in a staggered manner.
• Racing headers: A racing header is a high-performance header used in competition vehicles. The main aim of racing headers is to maximize power output. The racing headers also have a light-weight construction.
• Turbo headers: Turbo headers are designed to optimize the flow of exhaust gases to the turbine of a turbocharger. This is done through their short and direct routing design, which is able to reduce lag and improve boost response.

Specifications and maintenance of Miata headers

Before purchasing a Miata exhaust header, buyers should check the specifications to ensure it meets the requirements of their target market. Here are the common specifications:

• Material

  The material used to construct the Miata headers determines their durability and performance. Manufacturers use materials that can withstand high pressure and extreme heat from engine emissions. The headers are mostly made from stainless steel, carbon steel, or cast iron. Each material has its own benefits. For instance, stainless steel headers like the 1.8T stainless steel 4-1 long tube header have high resistance to corrosion and rust. They also look great, making them a good choice for cosmetic purposes. Carbon steel is affordable, while cast iron is durable and can withstand high heat.

• Style

  There are different styles of Miata headers, each with its own advantages. The most common styles are tubular and cast iron headers. Tubular headers are suitable for high-performance engines because they improve airflow and reduce back pressure. Cast iron headers are known for their durability.

• Number of cylinders

  Miata headers are designed to match the number of cylinders in the engine. Most Mazda Miata cars have 4-cylinder engines. Therefore, the headers are designed to work with 4-cylinder engines. Some high-performance Miata headers work with 6-cylinder engines to improve performance.

• Diameter

  The diameter of the tubes in the Miata headers affects the exhaust flow and sound. Headers with larger diameter tubes offer a free-flowing exhaust, which increases engine power. However, they produce a loud exhaust noise. Smaller diameter tubes create back pressure, which is suitable for small engines. The tube diameter usually ranges from 1 to 2 inches.

• Coating

  Coating improves the durability and performance of Miata headers. They are coated with different coatings to prevent corrosion and rust. Some headers also have heat-resistant coatings, which improve the lifespan of the product. The headers can also be coated with a ceramic coating. This improves their appearance and gives them a smooth finish.

There is no specific maintenance that needs to be done on Miata headers. However, users are advised to regularly check the headers for damage or wear. If there are any cracks on the headers, they should repair or replace them. This prevents further damage to the header and improves its lifespan. Another important aspect of header maintenance is to ensure proper installation. Unproperly installed headers can get damaged quickly.

How to Choose Miata Header

When choosing a Miata header for retail, it’s important to consider factors like the material used to make the header, the type of header, and the market needs. Here’s a breakdown of these factors:

Miata headers are made using different materials, each with its advantages. For instance, a cast iron Miata header is very durable, corrosion resistant, and can withstand high levels of stress. On the downside, it is heavy and has low exhaust flow. Stainless steel headers have high resistance to corrosion and are affordable. They also have high resistance to corrosion. However, they are prone to discoloration due to heat and are expensive. Titanium headers are lightweight and have high resistance to corrosion. They also have high resistance to discoloration due to heat. On the flip side, the headers are extremely painful due to their high costs.

Another consideration is the type of Miata header. There are two main types: the tubular and the cast headers. Tubular headers are made up of several individual tubes that are connected to the exhaust manifold. They are known for their high performance and are a great choice for race car drivers. Cast headers are made from a single, solid piece of metal. They are known for their durability and are a great choice for everyday drivers.

When choosing a Miata header, it is important to analyze the market needs to understand what the customers want. For performance, tubular headers are a better choice. However, they take a long time to cool down compared to cast headers. For everyday driving, cast Miata headers are ideal.

How to DIY and Replace Miata Header

Replacing the Miata's header can be a challenging DIY project, but it can be done with the right tools, materials, and mechanical knowledge. Here is a step-by-step guide to replacing the Miata header:

Tools and materials needed:

• New Miata header (compatible with the specific Miata model)
• Header gasket
• Exhaust bolts/nuts (if needed)
• Socket set
• Wrench set
• Torque wrench
• Screwdrivers
• Jack and jack stands
• Lug wrench
• Safety glasses
• Gloves

Steps:

• 1. Preparation:
• Ensure the Miata is parked in a well-ventilated area. Gather all the necessary tools and materials and wear appropriate safety gear, such as gloves and safety glasses.
• 2. Jack up the Miata:
• Use a jack to lift the Miata and secure it with jack stands. This will provide enough clearance to work under the vehicle.
• 3. Disconnect the battery:
• To prevent any electrical accidents, disconnect the negative terminal of the battery.
• 4. Remove the undertray:
• Some Miata models have an undertray that needs to be removed to access the exhaust system better. Use a socket or wrench to remove the bolts holding the undertray in place.
• 5. Remove the intake components:
• Depending on the Miata model and header design, you may need to remove some intake components, such as the intake duct and air filter, to gain better access to the exhaust manifold.
• 6. Remove the exhaust bolts:
• Use a socket and wrench to remove the bolts connecting the old header to the exhaust. Be prepared for some resistance, as these bolts may be rusted or seized.
• 7. Remove the old header:
• Remove the bolts securing the old header to the exhaust manifold. Carefully lower the header and remove it from the engine bay.
• 8. Clean the surface:
• Clean the mating surface on the engine where the header connects. Make sure there are no leftover gasket materials or debris, as this can cause leaks and affect the new header's performance.
• 9. Install the new header:
• Place the new Miata header onto the exhaust manifold and align it with the mounting studs. Carefully torque the nuts/bolts onto the studs, following the manufacturer's specifications.
• 10. Reassemble the components:
• Reinstall any intake components removed in step 5. Reattach the undertray if applicable.
• 11. Reconnect the battery:
• Reconnect the negative terminal of the battery. Double-check all connections and ensure there are no leaks or loose bolts.
• 12. Lower the vehicle:
• Remove the jack stands and lower the Miata using the jack.
