Having excess gases in your engine will slow it down. Hence we use headers, they help the engine release excess gases from the cylinders, and engine performance is greatly improved.
Long tube headers, in particular, because of their design, produce an aggressive sound while increasing the power and performance of the engine considerably.
This is because the design creates a negative pressure in the pipe, backflow pressure is reduced, and exhaust gases are easily pulled out. Buying a long tube header seems interesting, no?
However, remember to do your research properly and choose the best header according to your budget and its quality, which is why I have compiled a list of the best long tube headers for 5.3 Silverado for you.
1. Pacesetter 72C2265 Exhaust Header
My number one recommendation for your 5.3 Silverado today is the Pacesetter 72C2265 Exhaust Header. It improves the engine’s sound and performance to a great extent, and according to customer feedback, is a great product.
This metallic header does not peel off or discolor, which usually is the case when using black coat paints or chrome finishing. This is because a high-temperature curing process is used to spray Pacesetter’s Armor Coat, which has a three-year guarantee, the 2000-degree metallic ceramic coating.
Their coating is rust-free and resistant to corrosion, and it also can be easily cleaned. The header is CNC machined, containing port-matched thick steel flanges. These reduce any leakage or unrestricted flow going to the primary tubes. Slip fit collectors in this set give you three inches of space.
The CNC machined flanges are also extra thick, 3/8 inches to be exact. The advantage to this is better airflow, and the thicker they are, the better the flow is, and therefore the better the performance.
However, being thick could be a problem, making the product heavier and could weigh down your engine, but that is not the case here. The header weighs only 32 pounds.
These headers are very durable due to the 16-gauge carbon steel material used to make them, making them last you longer.
Mandrel-bent tubing inside it also helps the exhaust gases flow properly; optimization of the tube lengths also helps the engine perform high performance. This is also ensured as the tubes are connected to the collector in a proper firing way.
Furthermore, the installation process is fairly easy due to it involving only one piece. No welding or fabrication is required for installation, and you can easily do it with basic skills.
Therefore, you won’t need any professional help and can do it at home by yourself. Being 109 cm long, they will perfectly fit your Silverado’s engine.
