The 5.7L Hemi in your Ram 1500 is a powerful engine, but there's always room for improvement. Long tube headers are a popular modification for serious performance enthusiasts looking to unlock significant horsepower and torque gains. However, choosing the right set and understanding the implications is crucial. This comprehensive guide will explore everything you need to know about long tube headers for your 5.7 Hemi Ram 1500.
What are Long Tube Headers?
Long tube headers are exhaust manifolds that feature longer primary tubes than traditional shorty headers. This extended length allows for improved scavenging – the process of efficiently removing exhaust gases from the cylinders. This improved scavenging leads to better cylinder filling on the intake stroke, resulting in increased power and torque. The longer tubes also allow for a more optimized exhaust pulse, further improving performance.
Benefits of Long Tube Headers on a 5.7 Hemi Ram 1500
-
Increased Horsepower and Torque: This is the primary benefit. You can expect noticeable gains, typically in the range of 20-40 horsepower and a similar increase in torque, depending on the specific header design and other modifications.
-
Improved Exhaust Flow: The longer primary tubes offer less restriction compared to the factory manifolds, leading to a more efficient exhaust system.
-
Enhanced Engine Sound: Many enthusiasts appreciate the throatier, more aggressive exhaust note that long tube headers provide. This is often a significant selling point for many.
Drawbacks of Long Tube Headers on a 5.7 Hemi Ram 1500
-
Potential for Lower Low-End Torque (In Some Cases): While long tube headers typically offer significant gains at higher RPMs, some users report a slight decrease in low-end torque. This is less of an issue in performance-oriented applications, but worth considering for daily drivers.
-
Installation Complexity: Installing long tube headers is generally more complex than other bolt-on modifications. It often requires professional installation or significant mechanical aptitude.
-
Emissions Compliance: In many regions, modifications to the exhaust system must meet certain emissions standards. Long tube headers can potentially cause your truck to fail emissions testing, depending on local regulations. Check with your local authorities before installation.
Will Long Tube Headers Fit My Ram 1500?
This depends on the model year of your truck and any other modifications you've already made. Certain years and trim levels might have different chassis configurations that could impact compatibility. Always check the manufacturer's specifications to ensure a proper fit for your specific vehicle. Some aftermarket headers require additional modifications, like relocating the oxygen sensors or modifying the exhaust system downstream.
Do I Need a Tune After Installing Long Tube Headers?
Yes. Long tube headers significantly alter the air-fuel ratio and exhaust gas flow. Without a proper tune (ECU reflash or recalibration), your engine’s computer may not be able to compensate for these changes effectively. This can lead to poor performance, rough idling, and potentially damage to your engine. A custom tune tailored to your specific setup with long tube headers is essential to maximize the benefits and ensure safe operation.
What are the Different Types of Long Tube Headers?
Several materials and designs exist. Stainless steel is the most common due to its durability and corrosion resistance. Some manufacturers offer coated headers to further improve heat management and longevity. The design of the primary tubes and collectors also varies depending on the manufacturer and their specific performance goals.
How Much Do Long Tube Headers Cost for a 5.7 Hemi Ram 1500?
Prices vary significantly depending on the brand, material, and features. Expect to pay anywhere from $500 to $1500 or more for a high-quality set of long tube headers.
What About Catalytic Converters?
Long tube headers often require aftermarket high-flow catalytic converters to maintain proper emissions control and prevent any potential issues with oxygen sensor readings. These are typically sold separately.
This guide provides a comprehensive overview of long tube headers for the 5.7 Hemi Ram 1500. Remember to research thoroughly and choose a reputable manufacturer to ensure a quality product and a successful installation. Always consult a professional mechanic if you're not comfortable performing the installation yourself.
