OBX headers are one of the most critical parts of a car's exhaust system. They are the link between the engine cylinders and the exhaust pipes. The primary role of the header is to guide the exhaust gases out of the engine cylinders. With this in mind, there are three main types of headers.
When buying is300 obx headers, here are some specifications to consider:
The material used to make headers determines their performance and longevity. Most OBX headers are made of stainless steel or cast iron. Stainless steel headers are commonly used because they are long-lasting and resistant to corrosion. Additionally, they can withstand high temperatures and pressure that the exhaust produces. This makes them suitable for high-performance vehicles. Cast-iron headers are also long-lasting. However, they cannot withstand extreme heat as stainless steel. They are commonly used for normal driving on the road.
The diameter of the tube is also very important. It affects the flow of the exhaust gases. The larger the tube diameter, the more the exhaust gases that can flow out of the engine. This improves the engine's performance. However, if the diameter is too large, it will hamper the performance of the engine. The engine will have a decrease in power. Typically, maxima obx headers have tube diameters ranging from 1.5 inches to 2.5 inches. They are ideal for most cars.
When purchasing OBX headers, it is important to ensure they are compatible with the vehicle. This means the headers will be able to fit the engine of the car. The year, make, and model of the car should be considered when selecting headers. This ensures the headers have the right configuration to integrate with the exhaust system of the vehicle. The exhaust flange pattern and the position of the oxygen sensors should be compatible with the car.
Proper maintenance and care of OBX headers ensure that they last long and continue to perform well. Here are some tips on how to maintain the headers:
Check for leaks: Regularly check for any leaks in the headers. Leaks can reduce the performance of the vehicle and also cause the engine to make loud noises. When checking for leaks, look for any cracks or holes in the headers. If any damage is found, repair or replace the headers immediately. Also, ensure the fasteners are tight and secure.
Keep the headers clean: Clean the headers and the exhaust system regularly. Remove any dirt, debris, or rust that has accumulated. This prevents the headers from corroding. Use a soft brush to clean the headers so as not to scratch the surface. Also, avoid abrasive cleaning agents as they could damage the coating of the headers.
Protect the headers: To further protect the headers from rust and corrosion, considering applying a heat-resistant coating or paint. This will extend the lifespan of the headers. Also, inspect the coating from time to time to ensure it is still effective.
Check the gaskets: The gaskets between the headers and the exhaust system should be checked regularly. Ensure they are in good condition and not worn out. If any damage is found, replace the gaskets.
Inspect the O2 sensors: The oxygen sensors should be inspected regularly. Ensure they are working properly. In case of any fault, replace the sensors as soon as possible.
When buying OBX racing headers, it is important to identify the right ones for specific vehicles. Here are some factors to consider when selecting OBX headers.
It is important to consider the material used to make the header. Generally, headers are made of two types of materials: stainless steel and titanium. Stainless steel is a common material used to make obx exhaust header. It is durable and can withstand extreme conditions. Moreover, it is affordable. Titanium headers are ideal for high-performance vehicles. They are light in weight which allows the vehicle to have more horsepower. Titanium headers are also resistant to corrosion. However, they are more expensive than stainless steel.
Before buying OBX headers, ensure they are compatible with the vehicle's engine. Check the make, model, and year of the vehicle to purchase the right OBX headers. Using the wrong headers can damage the engine of the vehicle.
Check if the OBX headers have a coating. The main purpose of the coating is to protect the headers from corrosion. Some headers have a ceramic coating. They are ideal for vehicles that have high performance because they do not overheat. Coated headers are more durable than uncoated headers. This is because they prevent rust and corrosion.
The design of the OBX headers affects the performance of the vehicle. The two common designs of the headers are short and long tube headers. Short headers are less restrictive, which allows the exhaust gases to flow freely. As a result, the vehicle gets more horsepower. On the other hand, long headers are more restrictive. They are ideal for off-road vehicles. Select the design of the header that meets the needs of the vehicle.
Replacing exhaust manifolds with OBX headers is a precision operation that requires a high level of expertise. It is recommended to seek professional help from an experienced mechanic with advanced tools to install OBX headers properly. However, if the task is to be done, the following steps will guide the process.
Ensure the car is parked on level ground. Disconnect the battery to prevent electric shock. Wear protective gear such as gloves and goggles to guard against cuts and debris.
Use a floor jack and jack stands to lift the car safely to provide enough ground clearance and better access to the exhaust.
Remove the exhaust from the hangers and set it aside. Then unbolt the old exhaust manifolds from the engine.
Take off any heat shields and exhaust sensors, and set them aside for reuse.
Take out the old gaskets between the exhaust system and the engine. Ensure to remove all the debris.
Put new gaskets on the OBX headers and bolt them to the engine. Ensure the bolts are tightened evenly to prevent leaks.
Reinstall the exhaust, sensors, and heat shields. Ensure their connections are proper and secure.
Gently lower the car to the ground using a jack and remove the jack stands.
Start the engine and listen for any unusual sounds that could be leaks. If there are leaks, tighten the bolts and check again.
Run the engine and check around the OBX headers for any signs of smoke that could indicate leaks. If there are leaks, check the bolts and gaskets.
Q1: What is the difference between long-tube and short-tube headers?
A1: Short-tube headers are more similar to the factory exhaust manifolds. They are shorter and bolt up closer to the engine. On the other hand, long-tube headers have longer tubes that separate the exhaust pulses. They usually produce more low-end torque.
Q2: Do I need to tune my car after installing OBX headers?
A2: Most experts recommend tuning the engine after installing performance headers, even if the manufacturer says it's not necessary. This allows the ECU to optimize performance and ensure the engine runs smoothly.
Q3: Can I install OBX headers myself?
A3: It is possible to install headers with intermediate mechanical skills and proper tools. However, it is always recommended to consult a professional mechanic to avoid any installation errors and ensure optimal performance.
