Video Description:Check out this episode of Andy's Auto Sport TV where we explain all the basics about headers. In the video, we explain why headers open up horsepower gains and explain the difference between different types of headers. We also show how to install headers and then show the resulting horsepower gains with our dyno run results!

Q: What are the different tubing options for headers and what is the difference between them?
A: There are two major designs for headers: the 4-2-1 design and the 4-1 design. In many cases 4-1 headers are designed for racing applications where the vehicle is being driven at or near redline. The 4-1 design maximizes top end power, whereas the 4-2-1 evenly distributes it throughout the power band. Either way, you're going to be getting more horsepower from a header.
Q: What does a header do? Why buy a header?
A: An exhaust header is a performance product that replaces your factory exhaust manifold and improves an engine's performance by allowing air to flow more freely. The easier an engine breathes the more power it produces. Headers generally use piping with a wider diameter than factory tubing, which allows more air to pass through the exhaust system than factory. A header is one of the easiest bolt-on modifications you can make to increase horsepower, making an effective use of money if your goal is to quickly gain horsepower.
Q: For which vehicles is it necessary to buy a pair of headers? On your website are headers automatically sold in pairs for these vehicles?
A: When purchasing exhaust headers for a V-6 or V-8 engine, the header package is complete with two headers. If your vehicle is a 4-cylinder, there only a single header that is used.
Q: How much does the material used to make the header matter?
A: There are two main materials that headers are manufactured out of: ceramic and stainless steel. Ceramic headers are less expensive, but are prone to cracking if they get to be extremely hot. Stainless steel headers are more expensive but are more durable and generally more stylish. Stainless steel headers can take any kind of heat you throw at it and not prone to cracking.
Q: How do you install a header?
A: A header is a direct bolt-on. Simply remove the factory OEM exhaust manifold and the aftermarket header is put in its place. The header is to be attached the head of your vehicle. Remove all the bolts that hold the flanges in place and detach the factory manifold. The down pipe or exhaust pipe should be removed as well and then reattached once the header flanges are bolted back onto the head.
