Open headers

Types of Open Headers

Open headers are exhaust systems that are designed to reduce back pressure. This, in turn, increases the power and torque of a vehicle. They are popular in performance cars and racing vehicles. Open headers can be classified into two main categories: full headers and tri-y headers.

• Full headers

  Full headers are designed to replace the factory-installed exhaust manifolds. They are often used in high-performance vehicles. The main goal of full headers is to improve the car's overall performance by increasing the engine's horsepower and torque. These headers help to reduce the exhaust back pressure. As a result, the exhaust gases flow out of the engine block easily. Full headers also help improve the car's fuel efficiency. They are constructed from stainless steel, mild steel, or chrome-moly steel.

• Tri-y headers

  Tri-y headers are a type of exhaust header commonly used in high-performance and racing engines. These headers are designed to improve exhaust flow and increase engine performance. They achieve this by using a unique three-pipe design that merges the exhaust pipes in a Y shape. This design optimizes the exhaust scavenging effect, reducing back pressure and enhancing overall engine efficiency. Tri-y headers are particularly beneficial in applications where low-end and mid-range torque is essential, making them popular among car enthusiasts and racers seeking maximum performance.

Open headers can also be classified based on mounting:

• Full-length headers

  Full-length headers are open headers that run the entire length of the engine. They extend all the way to the bottom of the car. The main aim of these headers is to improve the car's overall performance by increasing horsepower and torque.

• Shorty headers

  Shorty headers are similar to full-length headers. However, they are only three-quarters of the length of full-length headers. These headers are less expensive and easier to install. Shorty headers are ideal for improving a vehicle's performance without incurring a huge cost or making extensive modifications.

• Mid-length headers

  Mid-length headers are open headers that fall between full-length headers and shorty headers. They are popular because they offer a good compromise between performance and cost.

Specifications and Maintenance of Open Headers

• Regular Inspection

  The first step in the maintenance of open headers is to regularly inspect the exhaust system. This includes open pipe headers, as it helps in identifying any signs of wear, damage, or corrosion. It is advisable to conduct these inspections on a regular basis or every time the vehicle is brought in for service. This practice ensures that the headers are in good condition.

• Cleaning

  Open headers should be cleaned regularly to prevent the buildup of debris and exhaust residue. When cleaning, it is important to use a mild detergent, and a soft brush, or cloth will do the work. This practice maintains the appearance and functionality of the headers.

• Tightening and Replacement of Hardware

  During the inspection, if loose bolts, nuts, or fasteners are found, they should be replaced immediately. This prevents leaks and ensures a secure connection between the headers and the exhaust system. Additionally, if any damaged or worn-out components are found, they should be replaced promptly.

• Heat Management

  It is important to ensure that proper heat management practices are followed. This includes checking the condition of heat shields and exhaust wrap, if applicable. These components help to protect surrounding parts from the intense heat generated by the headers.

• Lubrication

  If applicable, it is advisable to lubricate moving parts, such as valves or actuators, with suitable lubricant. This ensures smooth operation and prevents friction-related wear and tear.

• Professional Inspection

  It is important to open header users to have their vehicles inspected by a professional mechanic periodically. This is because professionals have the right tools and expertise to perform a thorough inspection. They also have the ability to diagnose any potential issues. They can also provide maintenance services to ensure the headers and exhaust system functions optimally.

How to choose open headers

With so many options available, it can be difficult to choose the right set of headers for a vehicle. Here are a few things—compatibility, durability, and performance—to keep in mind when choosing open headers.

• Compatibility

  Before anything else, buyers should ensure that the headers will fit the intended vehicle. This includes checking the make, model, and year of the vehicle. The header must also be compatible with the exhaust system and the engine.

• Material

  Open headers are made of different types of materials, such as stainless steel and mild steel. Each material has its own advantages and disadvantages. For instance, stainless steel headers are very durable and resistant to corrosion. On the other hand, mild steel headers are more affordable.

• Budget

  Buyers should get open headers that are within their budget. It is important to note that the headers with the best performance usually have a higher price point. In addition, buyers should consider the long-term costs, such as maintenance and installation.

• Ease of installation

  Some open headers are easier to install than others. For example, some come with all the necessary hardware for installation. If a header requires welding, buyers should consider getting one that is welded by an expert.

• Performance

  Different types of open headers provide different levels of performance. Buyers should consider the level of performance they want. For instance, if a high increase in horsepower is wanted, long tube headers are the best choice.

• Sound

  The sound produced by open headers varies depending on the type and design. Some headers produce a louder and more aggressive sound than others. If a quieter operation is preferred, buyers should look for headers designed to minimize noise.

• Legal regulations

  Buyers should ensure that the headers they purchase comply with local noise and emissions regulations. Some headers are designed to be street legal, while others are more suitable for track or race use.

How to DIY and replace open headers

It is advisable to have a professional install one's headers. However, it is a project that can be DIY-friendly. With the right tools and basic mechanical knowledge, one can install open header pipes successfully. Before starting the installation process, it is important to gather all the necessary tools and equipment needed for the job. This includes safety equipment such as gloves and goggles. Also, make sure the vehicle is parked in a well-ventilated area and on a flat surface. The vehicle should also be raised using a jack stand to provide access to the underside of the vehicle.

To install open headers, start by removing the old exhaust system. This involves disconnecting the exhaust pipes from the headers and removing any hangers or brackets holding the system in place. Once the exhaust system is removed, clean the surface of the headers where the open headers will be installed.

Next, position the open headers over the exhaust pipes and align them with the flanges. Ensure a proper fit to prevent any leaks or vibrations. Once aligned, use the bolts and nuts to secure the connection between the headers and the open headers. Tighten them evenly to maintain a proper seal.

After the headers have been successfully installed, start the vehicle and check for any leaks or abnormal noises. Make any necessary adjustments to ensure a proper fit and functionality. Depending on the type of vehicle, one may need to reprogram the engine control unit (ECU) to optimize performance with the new headers.

It is important to note that installing open headers can significantly increase exhaust noise. In some regions, it may be illegal to operate a vehicle with excessively loud exhaust. Always check local laws and regulations before making any modifications.
