- Headers are one of the most straightforward bolt-on accessories you can employ to boost the performance of an engine.
- The purpose of headers is to make it easier for the engine to push exhaust gases out of the cylinders by increasing the amount of space available.
- In How Car Engines Work, you can see that the engine produces all of its power during the power stroke, which is illustrated in the diagram below.
What Role Do Headers Play in an Engine? Headers, in particular, are intended to aid engines in eliminating exhaust gas from cylinders with the least amount of resistance possible. In How Car Engines Work, the engine completes one complete revolution after each stroke.

What do headers do in a car?
These components help to improve the flow of air into the engine while also reducing the flow of exhaust gas out of the vehicle. Headers are likely to be the most challenging of these components to install out of the box. Throughout this post, we’ll go over what headers are, how they work, and how much performance they may contribute to your automobile.
Do headers increase horsepower?
Although many people believe that adding headers to an engine is one of the most effective ways to improve horsepower, others disagree. Headers make it easier to eliminate dangerous exhaust gases from your engine, which in turn increases its efficiency and reduces emissions. Many people have noticed that installing headers on their engines enhanced both the power and torque.
What are the benefits of exhaust headers?
With the installation of exhaust headers, you are assisting your engine’s capacity to push gases through the cylinders more efficiently. Increased back pressure in the manifold is relieved as a result of this. Instead of pressure building up in the manifold as a result of several cylinders, a header is used to direct exhaust from each cylinder to its own exhaust pipe.
Why do headers have to be so big?
- The process of scavenging is dependent on the vacuum formed in the pipe, and a pipe with a diameter that is too big would restrict the impact of the suction.
- This is why engines actually produce greater power when headers are installed rather than when they are just vented directly to the atmosphere from the cylinder head.
- Which is preferable: shorty tube headers or long tube headers?
- That is dependent on the situation.
Do headers add horsepower?
Overall, a high-quality set of headers should result in a gain of roughly 10-20 horsepower, and if you keep your right foot on the brake, you may even notice a boost in fuel consumption.
Do headers make a car louder?
When compared to the factory exhaust manifold, automobile headers do not increase the volume of your vehicle’s exhaust. A cleaner-sounding exhaust system is provided by this aftermarket upgrade, which helps to improve the performance of your vehicle. The actual volume of the exhaust will not change as a result of this modification.
What is the purpose of headers on an engine?
- One of the functions of a vehicle header is to relieve back pressure that builds up in the manifold.
- Instead of a single exhaust pipe that is shared by all of the cylinders, each cylinder has its own exhaust pipe that joins to form a larger pipe known as the collector, which is located at the back of the engine.
- It is necessary to bend the individual pipes in such a way that they are all the same length.
Do headers make your car faster?
It is possible to gain 5 percent more horsepower by replacing the headers on your automobile, depending on the model and exhaust system that you have in place. And this isn’t a negligible step forward. When it comes to racing automobiles and cars with already strong engines, this effect might be much more noticeable.
Do headers require a tune?
- Likewise, when it comes to aftermarket exhaust headers, the answer is yes; you should tune your automobile after adding a new exhaust header.
- Major performance modifications, such as the installation of a header, can have a considerable impact on critical variables such as the air/fuel ratio.
- It is necessary to tune the header in order to get the most out of it while avoiding future difficulties.
How much do headers cost?
The cost of a header is determined by the number of cylinders in your engine, the sort of finish you choose, and the brand you choose. We have headers that start at approximately $200 and go all the way up to high-performance headers that cost more than $1,000. There is a solution for any engine performance enthusiast, regardless of their financial situation.
Do headers change exhaust sound?
Will it, however, improve the sound of your vehicle?! To put it simply, an exhaust header will somewhat increase the sound of your automobile when properly installed. When compared to the factory system, the new exhaust headers are broader and thinner. These features allow sound waves to travel more freely and exit the vehicle, resulting in a louder sound.
Do headers make your car pop?
According to Headers, there are distinct differences in the scavenging effects (i.e., the way each runner ″pulls″ gas from the exhaust port) as compared to the standard exhaust system, which was built as a balanced system to eliminate that popping sound at the tailpipe.
Is an exhaust manifold the same as headers?
The Differences Between Exhaust Manifolds and Headers (Recap) Exhaust manifolds are normally constructed of thick cast iron, whereas headers are often constructed of thin-walled stainless steel tubing. Exhaust manifolds have small inlets (which may be of varied lengths), whereas headers have lengthy main tubes that are all of the same length.
How much HP does headers and exhaust add?
So, how much horsepower do long tube headers contribute to the equation? If you use a manifold with a factory engine, you may expect to get around 6-9 horsepower.
What do headers connect to?
They are a common aftermarket item that are designed using stainless steel tubes for each cylinder, which makes it extremely effective at allowing gases to leave. The tubes on a header are connected to a collector pipe, which has the same length as the tubes on the header and is smooth.
Do headers waste more gas?
Exhaust headers are now significantly lighter. It has been demonstrated that exhaust headers that have been modified for efficiency can enhance gas mileage by a slight percentage on average. On the highway or in the city, this translates to an improvement of around 2-3 mpg. When compared to the level of performance they provide, this is little.
How much HP do headers add without Tune?
How Much Horsepower Do Headers Add Even If They Aren’t Tuned? If headers are fitted without a tune, the horsepower gain will be restricted, and the engine will run lean as a result of the lean running. After installing headers and modifying your vehicle, you may expect to gain up to 50 horsepower.
Why are long tube headers illegal?
16 Long Tube Headers are used in this project. It is also prohibited, according to the Environmental Protection Agency, to tamper with your car’s emissions since it is deemed interfering with your vehicle emissions. In most cases, drivers will get away with it as long as your catalytic converter and oxygen sensors are still in good working order.
Which headers are best?
– These stainless steel headers are designed to be flush with the vehicle. – Compatible with both angled and straight plug heads – Simple to install – TIG welding is used to fuse the pieces together – Built-in hole for the oxygen sensor – Provides a more effective method of exhaust gas evacuation.
What are the best headers?
- For that authentic NASCAR appearance, invest in a pair of performance exhaust headers with a ceramic coating.
- Consider purchasing a matched set of headers for an engine compartment that already has certain performance enhancements.
- Installing a pair of nickel-chrome or stainless steel performance exhaust headers will give your vehicle a more noticeable look.
What do headers do on a vehicle?
- Long Tube Headers are a type of header that is longer than the tube itself. This sort of header has a ‘4-1’ configuration, which means that four main tubes exhaust air into a single collector pipe.
- Headers that are not too long. Shorty headers, as the name implies, make use of four main tubes that finally merge into a single collector pipe.
- Headers that are mid-length.
- Headers with three Y’s.
