How Hot Do Headers Get?( For Each Header Type )

As you know, the engine is the essential part of the car. It directly affects the performance of the vehicle. For the engine to operate stably and save fuel, your engine needs some changes related to the Header. The following article will give you an overview on how hot do headers get.

Benefits Of Replacing The New Header

Replacing the new Header will bring many benefits to your vehicle. The first effect is to increase engine performance, and you will get rid of the sluggish car when accelerating.

Besides, the new Header will help save fuel significantly and prolong the life of the engine. However, replacing the new Header will require car compatibility with the device. You should use the car manual to be able to choose the proper Header for your vehicle.

In terms of characteristics and structure, headers are divided into 4 types: Long Header, medium header, short Header, and Tri-Y Header.

Types Of Current Car Headers

Long Header

Long headers are the first category, and they are the longest of the four header types. Usually, the long Header is for the main ducts on the exhaust.

With this type, the capacity will be significant in power, even in low, medium RPM ranges. At the same time, they also help your vehicle reduce the risk of air escaping from sucking back into another pipe.

Compared to short headers, long ones can provide up to about 10 to 20 horsepower. When you move your vehicle over long distances, a long header will save you more fuel than a short header.

Short Header

If your vehicle has a modest size, using a short header is a perfect choice. However, you need to consider the appropriateness of the short Header for the car before proceeding with the replacement.

Usually, a short header is a line of spray pipes that you can easily install without too much experience. Short headers do not generate as much power; they are concentrated in the mid and low range compared with long ones.

Medium length header

Medium headers are a mid-range solution compared to short and long headers. It can produce a lot of mid-range and low-range torque. Also, the medium Header will generate more even power than the short deader.

Header Tri – Y

Header Tri-Y is a less common injector than the other three classifications. This Header will merge four main pipes into two larger sub pipes for Tri-Y before combining them into one manifold.

The secondary pipe will have the role of helping the exhaust gases maintain a steady speed before they enter the collector. From there, exhaust gases will circulate more efficiently, and engine performance will be significantly improved.

The essence of replacing the large Header and helping the engine circulate better air will result in significantly improved performance and maximum fuel savings. So what is the working principle of the Header?

In terms of a car’s 4-stroke cycle, you’ll find that the engine can generate all of its power during the entire journey. Usually, the gasoline in the cylinder will burn and expand during running.

During discharge, the engine may lose power due to backpressure. At that time, the piston will push the exhaust gas out of the cylinder.

In some cases, the piston may encounter some resistance that will reduce power. To limit that trait, the car will need 2 exhaust valves instead of a single exhaust valve because it will make the exhaust opening larger to promote exhaust gas flow.

As the exhaust gases exit the cylinder, they travel from the engine into the pipeline to the catalytic converter.

The exhaust gas then travels to the car’s silencer. Sometimes, back pressure will occur when the exhaust gas increases the pressure of the manifold. To limit it, you need to put a header because it will help eliminate the backpressure of the manifold.

The gas pulse usually has its mass. So, as the gas pulse moves down the tube, it builds momentum. Closing the relief valve will help you stop that pulse flow for a short period. And it will keep moving as the exhaust moves.

As the pulse moves, a vacuum is created behind the pulse. If the exhaust valve is open, the vacuum will suck the exhaust gas out of the chamber, improving the engine’s ability to let the air out.

At the same time, it is also at this time that the vacuum will draw clean air through the intake valve and create an entirely different effect with the combination of mild forced induction. When the engine has more clean air, more power will be generated. That is one of the main benefits of the Header besides the limited use of backpressure drop.

Some Frequently Asked Questions

Should you wrap the Header?

The answer is yes. You should wrap the Header because it will keep the heat of the pipe. From there, the exhaust air will circulate better and remove dirt during travel. In addition, the header wrap also helps to reduce the temperature, and then the heat will be retained inside the wrapper and not cause overheating of the surrounding components.

How does the turbocharger heat up?

Usually, the temperature of the muffler is between 300-500 degrees F. This is just an average temperature. The muffler can handle temperatures up to 1200 degrees F. The catalytic converter may fail when the temperature exceeds the allowable threshold.

What temperature will the discharge head normally reach?

Car exhaust pipes can reach temperatures up to 1200 degrees F. Normally, and exhaust pipes will not get such high temperatures. Locations, where such temperature thresholds can be found, are areas of tightness or obstruction of exhaust gases.


Hopefully, the article will help you distinguish the 4 types of headers and understand how they work. Each vehicle type will be suitable for a different type of Header. You should use your car’s manual to determine exactly what kind of Header is right for your vehicle.
