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!

Video Description:In this episode, we interviewed Shawn Gibson from Gibson Performance! Here are some of the highlights from the video:
*At 1:21, he talked about how Gibson's goal with their exhaust systems is to give you power gains and torque gains without giving you an overbearing sound inside your vehicle.
*At 2:50, he talks about their 100,000 square foot facility in California and the types of R&D and engineering they do their for their products. They also manufacture all their parts in that facility.
*At 3:19, they talk about how they do bending, welding, polishing, tipping, coating, and all other phases of the manufacturing all in house so that they have total control over the quality of every product they make.
*At 5:50, they talk about how Gibson products come with a lifetime warranty, and why they're able to offer a warranty like that.
*At 6:37, he talks about how Gibson headers are made using the thickest gauge material, and the different coatings of header options they have available. He also explains how their headers come with the gaskets and bolts, so customers will have everything they need to install it.
*At 7:30, Shawn urges customers to check out AndysAutoSport.com for Gibson products!
*At 8:03, he talks about how Gibson and Andy's Auto Sport working together makes purchases easy and smooth for customers!

After finding various methods to increase performance through improved muffler designs, the Gibson family began and expanded their business into one of the largest and most trusted aftermarket performance exhaust companies around.
Now, with a host of engineers and technicians, Gibson Performance is larger than ever, but it has not lost its commitment to building cost-effective exhaust systems that deliver more performance for the dollar. This includes designing exhaust systems that make more power across a wide RPM band, where enthusiasts need it. High peak horsepower gains are important, but Gibson decided that making horsepower and torque in the lower RPM range would benefit customers who want more towing power, passing acceleration, and improved fuel economy.
Every Gibson product is also designed for hassle-free, bolt-on installation with professional-looking results. Furthermore, all of Gibson's street applications are 50-state emissions legal and do not affect the factory warranty.

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: 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 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.
