Best Headers for 5.3 Silverado Reviews 2021 – Buying Guide
Selecting 5.3 Silverado headers is a do-or-die situation. Because it is such an addition that can either improve or decline your vehicle’s engine’s performance. Therefore, choosing the right one with proper knowledge about long tube headers for Silverado is crucial.
To increase your vehicle’s performance, the engine needs to exhaust properly. That can only happen when you buy the tube headers that allow maximum airflow so that the engine can exhaust and breathe quickly. How freely tube headers exhaust airflow depends on their build quality. So, choose a wide header.
Material and Finishing
Material and finishing of the tube headers can tell about their longevity. If you don’t want to replace tube headers every month, which is time-consuming and costly, you have to spend on durably building ones with external protection included.
Carbon steel, stainless steel are considered robust, and having some sort of coating externally prevents the tubes from rusting and peeling.
Length of the header
The header length will determine your vehicle’s engine power. Short and compact headers are less efficient, so they do not let the engine move faster.
Whereas, longer tubes make the engine run quite fast and are good for high-speed racing. So, choose the length according to your need.
Permission on streets
Although it may sound invalid, some headers are not permitted everywhere because they enable high-speed driving. So, make sure the header you buy has permission to operate in your city.
The header installation is not tough at all. Moreover, they come with all the hardware and instructions for ease that someone who has basic knowledge can do it with ease.
However, before you buy the header make sure to check whether it fits the cavity made in your car or not.
Types of headers for cars- What are the different types of headers?
There are some different types of headers. Among them, “full-length” and “shorty” headers are most common. There are some general categories of headers – lakester style, full-length headers, shorties, and tri-Y.
The Two Types of Tube Headers (Manifolds)
Short Tube Headers
The short tube header is short compared to the long tube headers, but it has a much longer tube. The port pipes merge into the single exhaust pipe in a much shorter distance in the short headers. The 5.3 l headers, which are short, offer the best performance in the idle to the RPM range.
It makes the shorty headers the perfect headers for vehicles that rely on the low RPM range, such as the daily commuter or the work pickup that see a lot of hauling and towing. The short tube headers are designed to bolt right up with the exhaust that allows easily bolt in the set of headers without having to worry about the custom fabrication or having to move the stock emissions equipment like the catalytic converter.
The shorty header is appropriate for the turbo-boosted engine as well as it is perfect for the improved performance for the daily driver or the commuter. It is comparatively easier to install as it requires less space than the long tube.
The short tube header is fairly inexpensive. It is preferable only by using a turbo setup, but it can still be used in street builds and naturally aspirated engines.
Long Tube Headers
The exhaust pipe is much longer, and it merges farther out in the long tube headers. It makes lower exhaust backpressure, and the Chevy 5.3 headers improve oxygen intake as well as boost horsepower.
The full-length header makes a ton of power in the high RPM range to mid RPM range. But it is not necessarily street legal that depends on the emission standards. The installation process of the long tube headers for 5.3 Vortec is complicated.
The Silverado long tube headers are the best option for track terrors and high-rev vehicles. All extra space they require in the engine compartment demand some costly configuration.
The headers for 5.3 long tubes are generally considered the best to reduce the backpressure and scavenging. It typically flows less than the shorty headers.
The installation is more challenging as it is too long to work with the exhaust’s existing component. It is preferable only by using a non-turbo setup performance build as it produces higher performance numbers compared to its cost.
Pros and cons of headers
- The headers reduce the back pressure of the manifold.
- Headers improve the performance includes horsepower, fuel mileage, etc.
- 5.3l headers are great for the turbos.
- The exhaust headers enhance high revving.

- There tend to leak.
What headers do for a car?
For improving the performance of the engine, the header is one of the most comfortable bolt-on accessories. The aim of the header is making easier to push exhaust gases out of its cylinders.
The Silverado headers also make the car sound much louder. The ceramic-coated heater helps to keep the heat in the exhaust gas than the seep out.
It prevents leak speeds of heat, the expulsion of the exhaust out the tailpipe, and the headers improve the efficiency of the engine by decreasing backpressure. The headers are the most significant gains to the car. The exhaust heater reduces the back stress of the manifold.
One of the essential aspects of the smooth Silverado header installation is following the appropriate procedure to ensure the longevity of the gasket. If you want to ensure trouble-free sealing, you should make sure the gasket is made of a material that can withstand high temperatures and will be exposed.
Doug’s gaskets may ensure a trouble-free installation. Another essential issue for the leak-free operation is the way of installation of the header gasket. To install the gasket, you should follow the installation instructions.
You should make sure that the car completely cools down before starting the installation process and get ready with installation requirements. There has only one way to fit the lower gasket. The pattern of GM’s bolts is irregular. The professional installation of the gasket is recommended.
To install the headers, you should follow some steps, and these are the following –
- At first, you should install the headers and gasket, as well as you should tighten the bolts tight. Then you should run the engine and should allow the headers to get hot.
- After this, shut the engine down.
- When the header is still hot, you should again tighten the header bolts.
- Now you should run the car for 200 to 300 miles.
- When the header is still hot, you should one more time tighten the header bolts.
If you follow the procedure, the vehicle’s header bolts should stay tight, and the vehicle’s gasket should last several years. Rechecking the bolts is a good idea to make sure that everything is ok and remains tight.
Exhaust Headers vs. Manifolds
The exhaust manifolds generate back pressure that reduces overall performance because every cylinder has its tube. In contrast, a header reduces this problem because the headers allow the gas to exit without any backpressure.
Exhaust Headers are the alternative to using the exhaust manifold. Exhaust manifolds consisted of cast-iron and were included in the trucks and factory cars, whereas exhaust headers include stainless steel for every cylinder.
The exhaust manifolds are relatively inexpensive and easy to install, whereas headers are expensive and difficult to install. The exhaust manifolds can withstand the high pressure and heat associated with the gases.
The exhaust headers create noise as it is thinner than the exhaust manifolds. The exhaust manifolds reduce the engines’ efficiency and horsepower, while the exhaust headers increase the overall performance of the machine.
The exhaust manifolds materials cast iron are cheaper. Still, it is not the most robust material, whereas stainless steel is the exhaust headers’ material is the expensive but most vital material.
The main difference between the exhaust manifolds and the exhaust headers lies in their sound and performance. The exhaust manifolds have less space for passing gases, whereas the exhaust headers have more freedom.
The exhaust manifold absorbs more sound in contrast to the exhaust header, which absorbs less sound.

The hooker headers can increase in torque and power which will rise from 3000 rpm to 6000 rpm.
Are long tube headers louder than shorty headers?
When you will have a comparison to your stock exhausting manifold, then you will find the shorty headers will have a longer tube.
If your header’s length is unequal, then it will offer a disturbing sound with a little low-end torque. But if your header’s length is equal, then it will offer great and consistent performance gains.
Are long tube headers worth it?
Yes, long tube headers are worth every penny because they have an advantage that will not only provide peak power numbers but also help you to increase torque and horsepower at the same time in the mid-range and low range of the RPM band.
