When it comes to upgrading the exhaust system of your 5.7 HEMI, headers are one of the most impactful modifications you can make. Headers play a key role in optimizing engine performance by improving exhaust flow. But which headers are the best for a 5.7 HEMI? This guide will help you navigate the differences between shorty and long tube headers, their performance gains, installation considerations, and which brands offer the best value for your HEMI.
Introduction to Headers for a 5.7 HEMI Engine
Headers are an essential component in any performance exhaust system. Their job is to collect exhaust gases from each cylinder and direct them into the exhaust system. For a 5.7 HEMI engine, choosing the right set of headers can significantly enhance both horsepower and torque by improving the flow of exhaust gases.
The primary function of headers is to reduce the restriction that stock manifolds create. By providing a more efficient path for the exhaust gases to exit the engine, headers can increase engine efficiency, resulting in noticeable performance improvements. For a 5.7 HEMI, upgrading to headers is often one of the first steps in boosting performance.
Shorty Headers vs. Long Tube Headers for 5.7 HEMI
When it comes to headers for the 5.7 HEMI, there are two primary types to consider: shorty headers and long tube headers. Each offers distinct advantages, depending on the driving experience and performance goals.
Shorty Headers – Key Benefits
Shorty headers are a more compact design, closely resembling the stock exhaust manifolds. They’re relatively easy to install, making them a great option for DIY enthusiasts or those looking for a straightforward upgrade. Since shorty headers don’t require major modifications to the engine bay, they are also less likely to interfere with other parts of the engine.
These headers generally provide moderate performance gains, especially at lower RPMs. They are a solid choice for daily drivers who want to enhance exhaust flow without radically altering the vehicle's characteristics.
Long Tube Headers – Key Benefits
Long tube headers are designed to offer maximum exhaust flow by having longer tubes that allow the exhaust gases to travel further before entering the rest of the exhaust system. These headers are ideal for high-performance applications, as they provide significant horsepower gains, particularly in the mid to high RPM ranges.
While long tube headers offer superior performance gains, they can be more challenging to install and may require additional modifications. These headers are perfect for those looking to increase overall horsepower and optimize their HEMI’s power potential.
Which One Should You Choose?
The choice between shorty and long tube headers largely depends on your intended use. If you’re looking for a performance boost primarily for street driving with minimal installation hassle, shorty headers are the way to go. However, if you’re aiming for maximum power, especially for track use or high-performance builds, long tube headers are the superior option.
Performance Gains from Upgrading to Headers on a 5.7 HEMI
Upgrading to headers can significantly enhance the performance of your 5.7 HEMI engine. Let’s dive into the potential performance gains with both shorty and long tube headers.
Power Gains from Shorty Headers
Shorty headers provide a noticeable performance improvement, especially in the low to mid-range RPMs. Although they don’t provide the dramatic gains seen with long tube headers, they can still offer around 10-15 horsepower depending on the quality of the headers and other supporting mods. For many street-oriented drivers, this increase in power is more than sufficient.
Power Gains from Long Tube Headers
Long tube headers, on the other hand, can add significant horsepower, particularly in the higher RPM ranges. The design of long tube headers allows for better scavenging, which helps in improving exhaust flow and reducing engine backpressure. On a 5.7 HEMI, you can expect a gain of 15-30 horsepower with long tube headers, especially if combined with other performance modifications like a cold air intake or ECU tuning.
Performance Benefits at Different RPM Ranges
The key to choosing the right header lies in understanding how they perform at different RPM ranges. Shorty headers tend to enhance performance at low to mid RPMs, making them ideal for daily driving. Long tube headers, however, shine in the high RPM ranges, where their extended length allows for better exhaust scavenging, making them perfect for racing and performance driving.
Choosing the Right Headers for Your 5.7 HEMI
When selecting the best headers for your 5.7 HEMI, it's important to consider several factors, including your driving needs, other modifications, and budget.
Consider Your Driving Purpose
The first consideration when choosing headers is how you plan to use your vehicle. If you primarily use your HEMI for daily driving or cruising, shorty headers will be more than adequate. They provide a modest increase in power without compromising drivability.
However, if you’re building a high-performance vehicle for track days or racing, long tube headers will give you the edge you need. These headers are designed to maximize power at higher RPMs and deliver superior performance in a race environment.
Matching Headers with Other Mods
If you’ve already modified other parts of your engine, such as the intake or the ECU, it's important to select headers that complement those upgrades. For example, if you've installed a cold air intake or a forced induction system, long tube headers may be the best option to take full advantage of the increased air intake.
Installation Considerations for Headers on 5.7 HEMI Engines
Installing headers on your 5.7 HEMI is a relatively straightforward process, but it’s not without challenges. Here’s what you need to know before beginning the installation.
Shorty Headers Installation Process
Installing shorty headers is generally simpler than long tube headers. The compact design means they often bolt right into the stock manifold locations without the need for significant modifications. This makes shorty headers a good choice for those who want a quick performance upgrade without the need for advanced mechanical knowledge.
Long Tube Headers Installation Process
On the other hand, long tube headers require more work. They are typically more complicated to install, often requiring removal of components like the catalytic converters or parts of the engine bay. Additionally, you may need to modify your exhaust system to accommodate the longer pipes. It's often recommended to have long tube headers installed by a professional to ensure proper fitment and to avoid damaging other components.
Tuning After Installation
Once headers are installed, especially long tube headers, tuning your engine is crucial. The enhanced exhaust flow can significantly change the air-fuel ratio, so reprogramming your ECU is often necessary to optimize performance and ensure the engine runs smoothly.
Cost and Value: Is It Worth Upgrading Your 5.7 HEMI’s Headers?
Upgrading your headers is an investment, and understanding the cost and value is key to making an informed decision.
Cost of Shorty Headers
Shorty headers are generally less expensive than long tube headers, with prices ranging from $300 to $600. Given their relatively simple design and easier installation, they provide a great balance of cost and performance for many drivers looking to enhance their engine without breaking the bank.
Cost of Long Tube Headers
Long tube headers are more expensive, typically ranging from $600 to $1,200 depending on the brand and materials. The higher cost reflects their superior performance gains and the increased complexity of the installation process. If you're looking for significant horsepower gains, the investment is often worth it.
