The Best Header for 5.3 Silverado Buying Guide 2021
Choosing a header for your Silverado is a critical decision because it is such an upgrade that uplifts the performance of your vehicle. Besides, it is a bit costly too. So, getting a header that doesn’t support your reason behind purchasing it is not a good thing.
To buy one of the best headers for 5.3 Silverado, there are a few things that you must check. Here I’m going to talk about the things that I’ve checked while choosing a long tube header. Hope it’ll help you to choose yours.
You may buy the best exhaust header in the market, but if that is not compatible with your vehicle, you are on the losing side. Before buying a header, at first make sure that it is compatible with your vehicle model. Websites give you chance to check the compatibility. If you purchase offline, ask the salesperson about it. You’ll get the answer.
While buying a header, make sure that it allows the exhaust gas to flow freely. Headers with minimum airflow restriction ensure that the exhaust gas goes out quickly so that the engine can breathe properly. As a result, the performance of the vehicle increases. Airflow restriction mostly depends on the design and build of the header.
I’ve seen some headers that don’t have permission on streets in some states. So, before choosing a header, please make sure that it has permission in the state you live. Otherwise, you may face problems. Maximum headers have permission in maximum states. But for being sure, you should check it.
Length of the header
Size matters everywhere. It is true for choosing a header too. If you want a great exhaust haul, go for short headers for 5.3 silverodo because those are compact. On the other hand, choosing a long exhaust header will ensure more power for fast driving. Know your requirement and then choose one according to that.
Material and Finishing
Material is important while buying a header because headers are long term investment. Good material ensures strength and durability. Durability is also ensured by the finishing. Inappropriate finishing may not restrict rust build-up. As a result, your exhaust header won’t last long. So, keep eyes on these too.
This is another criterion you should focus on. Go for easy to install headers. Headers come with bolt-on installation are very easy to install and allows you to do the task. Here you should see another thing. Make sure that your vehicle has enough room to place the header. If there is not, you should not choose the header. Also, sometimes installing a header may require a bit modification. In that case, let a professional or experienced person do the task.
These are the things I focus on while buying headers for me or my near ones. You can also look for a few more things like warranty, price, and so on.

Frequently Asked Questions (FAQ)
Do long tube headers really give more horsepower?
Answer: Horsepower depends on different things. But long tube headers have impact on your vehicle’s horsepower. Long pipes create less back pressure in your vehicle’s exhaust system. As a result, the engine gets enough chance to use the HP properly. In medium and high RPM vehicles, you’ll get better results. In low RPM vehicles, the result is a bit less but you’ll feel it.
Do headers make vehicles sound louder?
Answer: Yes, headers make the vehicles sound louder than regular. Short headers do the task better than long headers. But, a header is only one part of the exhaust system, there are so many. So, the header only won’t increase the sound that much. You’ll notice an increase though.
Is a header expensive?
Answer: There are different headers in different price ranges. The better the header is, the more the price. But overall, adding a header is comparatively a costly upgrade in maximum cases. So, it is better to keep your eyes open and invest some time to pick one.
