The 5.7L Hemi engine is a renowned powerhouse, offering ample performance for muscle car enthusiasts and truck owners alike. However, for many who want to push their vehicle's potential even further, aftermarket modifications are often the key. One of the most common upgrades for improving engine performance is the installation of exhaust headers. But how much horsepower (HP) do headers add to a 5.7 Hemi, and are they worth the investment? In this article, we will break down the effects of headers on a 5.7 Hemi engine, compare short-tube vs. long-tube headers, and explain how these upgrades can boost both horsepower and torque. Understanding the Role of Exhaust Headers Before delving into how headers affect your 5.7 Hemi’s horsepower, it’s essential to understand what exhaust headers do and how they impact your engine’s performance. Exhaust headers replace the stock exhaust manifolds, allowing exhaust gases to flow more freely from the engine. These headers are designed with individual tubes for each cylinder, which merge into a single pipe. This design minimizes exhaust backpressure, which reduces restrictions and allows for better airflow. The result of this more efficient exhaust flow is improved engine performance, particularly in terms of horsepower and torque. While stock exhaust systems can limit the amount of air an engine can expel, headers allow for smoother exhaust flow, meaning the engine doesn’t need to work as hard to expel gases. As a result, more energy is directed toward power generation, which leads to increased performance.   How Much HP Do Headers Add to a 5.7 Hemi? The horsepower increase from headers can vary depending on several factors, including the type of headers used, the condition of the engine, and whether any other modifications are made alongside the headers. On average, exhaust headers can add between 10 to 30 horsepower to a 5.7 Hemi engine. Here’s a breakdown of how different types of headers influence performance: - Short-Tube Exhaust Headers: These are the most commonly used headers for vehicles looking for a modest increase in power without requiring too many other modifications.
