Yes, most exhaust shops will install headers, but the process can be complex and varies by shop. It involves removing the stock exhaust manifold, fitting the headers, and ensuring everything is properly sealed. Some shops may refuse the job due to legal restrictions or the expertise required, so it’s important to find a shop experienced in this type of installation.
Headers are a popular performance upgrade for car enthusiasts looking to increase their vehicle’s horsepower and torque. They replace the stock exhaust manifold and help improve the engine’s ability to expel exhaust gases. But while many car owners are interested in installing headers, one of the most common questions that arises is: Will exhaust shops install headers?
Contents
What Are Headers, and Why Install Them?
Headers are aftermarket parts designed to replace a vehicle’s standard exhaust manifold. They are usually made from stainless steel, mild steel, or ceramic-coated metal and have individual tubes for each engine cylinder that merge into a single collector. Unlike a stock exhaust manifold, headers are designed to reduce backpressure and improve exhaust gas flow, allowing the engine to “breathe” more freely.
Benefits of Installing Headers
Installing headers offers several benefits:
- Increased Horsepower and Torque: By improving exhaust flow, headers reduce backpressure and enhance engine efficiency, leading to noticeable gains in horsepower and torque.
- Better Fuel Efficiency: More efficient exhaust flow can result in better fuel combustion, potentially improving fuel economy.
- Enhanced Sound: Headers can give your car a deeper, more aggressive exhaust note, which is often desired by car enthusiasts.
- Heat Reduction: High-quality headers often reduce engine bay temperatures by expelling hot gases more effectively, which can help preserve other engine components.
Will Exhaust Shops Install Headers?
The short answer is yes, most exhaust shops will install headers, but there are some important considerations to keep in mind. Header installation is more complex than replacing a standard exhaust part, like a muffler or catalytic converter, due to the following factors:
- Complexity of Installation: Installing headers involves removing the existing exhaust manifold, attaching the new headers, and ensuring all connections are secure and leak-free. This process may require modifications to other parts of the exhaust system, such as the catalytic converter or oxygen sensors.
- Vehicle Compatibility: Some headers are designed to be a direct bolt-on replacement for the stock exhaust manifold, while others may require custom fitting or modifications. Exhaust shops need to determine if the headers you’ve chosen are compatible with your vehicle.
- State Emissions and Noise Regulations: Depending on where you live, there may be legal restrictions on installing aftermarket headers, particularly if they affect the emissions control system. Exhaust shops will usually check the headers’ compliance with local regulations before agreeing to install them.
- Labor Costs and Time: Header installation is a labor-intensive process that can take several hours, depending on the vehicle and header design. This will factor into the cost and whether a shop is willing to take on the job.
- Experience and Expertise: Not all exhaust shops have experience with header installations, especially for high-performance or exotic vehicles. It’s crucial to find a shop with the right expertise for your specific make and model.
What to Expect When Getting Headers Installed at an Exhaust Shop
If you decide to have an exhaust shop install headers on your car, here’s what you can typically expect from the process:
- Initial Consultation and Inspection: The shop will first inspect your vehicle and the headers to ensure compatibility. They will check for potential clearance issues, required modifications, or additional parts needed, such as new gaskets or bolts.
- Estimate and Cost Breakdown: Once the inspection is complete, the shop will provide you with an estimate for the installation, including labor costs, any necessary parts, and potential extra costs for custom fabrication or modifications. Header installation can range from $300 to $1,500 or more, depending on the complexity of the job and the vehicle type.
- Installation Process:
- Removal of the Existing Exhaust Manifold: The first step is to remove the stock exhaust manifold. This can be challenging due to rusted bolts or hard-to-reach areas.
- Fitting the New Headers: The headers are then aligned and fitted to the engine block. This step often involves custom fitting or adjusting other parts of the exhaust system.
- Securing Connections: All connections are tightened, and any necessary gaskets or seals are replaced to ensure no exhaust leaks.
- Modifying the Exhaust System: Depending on the header design, modifications to the downpipe, catalytic converter, or oxygen sensor placement may be required.
- Testing and Tuning: After installation, the shop will start the vehicle to check for leaks or unusual sounds. They may also perform a dyno test or ECU tuning to optimize performance and ensure the car is running correctly with the new headers.
- Compliance Check: If you live in an area with strict emissions laws, the shop may conduct an emissions test to ensure the vehicle meets local standards.
How to Find Right Exhaust Shop for Header Installation
Not all exhaust shops are created equal. To find the right shop for your header installation, consider the following tips:
- Look for Specialized Experience: Choose a shop that specializes in performance upgrades or has experience with your specific make and model. Shops that frequently work with high-performance or custom vehicles are more likely to have the expertise needed for header installations.
- Check Reviews and References: Look for customer reviews online or ask for references. Positive feedback from other car owners who have had similar work done is a good sign.
- Ask About Warranty and Guarantees: Ensure the shop offers a warranty on their labor and the parts they use. This will protect you in case of any issues after the installation.
- Inquire About Certification: Look for shops that employ certified technicians, such as ASE (Automotive Service Excellence) certified professionals. Certification indicates a level of expertise and professionalism.
- Compare Quotes: Get quotes from multiple shops to compare prices, services, and experience. While cost is a factor, the cheapest option may not always be the best.
Challenges in Header Installation
Header installation is not without its challenges. Some common issues that may arise include:
- Fitment Issues: Not all headers fit perfectly, especially if they are not designed specifically for your vehicle model. In some cases, modifications may be necessary to make the headers fit correctly.
- Exhaust Leaks: Improper installation or failing to use new gaskets and seals can result in exhaust leaks, which can cause a drop in performance, unpleasant noises, and even potential engine damage.
- Oxygen Sensor Problems: Many vehicles have oxygen sensors located near the exhaust manifold. Installing headers may require relocating these sensors or extending their wiring, which can be complicated.
- Heat Management: Headers tend to run hotter than stock exhaust manifolds. This can lead to increased engine bay temperatures, potentially affecting other components. Heat shields or ceramic coatings may be necessary to manage this heat.
- Compliance Issues: In some regions, installing aftermarket headers may not be street-legal, particularly if they interfere with emissions controls. Always check local laws before proceeding.
