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 among enthusiasts seeking to unlock significant performance gains. This comprehensive guide dives deep into the world of long tube headers for the 5.7 Hemi Ram 1500, exploring their benefits, drawbacks, considerations, and frequently asked questions.
What are Long Tube Headers?
Long tube headers are exhaust manifolds that replace the factory-installed units. Unlike shorty headers, which are compact and close to the engine, long tube headers extend further down, typically past the front axle. This longer length optimizes exhaust scavenging, leading to increased horsepower and torque.
Benefits of Long Tube Headers on a 5.7 Hemi Ram 1500
The advantages of installing long tube headers on your 5.7 Hemi Ram 1500 are numerous:
-
Increased Horsepower and Torque: This is the primary benefit. By efficiently evacuating exhaust gases, long tube headers allow the engine to breathe more freely, resulting in noticeable power gains throughout the RPM range. You can expect gains ranging from 15-30 horsepower and a similar increase in torque, depending on the header design and supporting modifications.
-
Improved Throttle Response: The enhanced exhaust flow translates to a more responsive throttle, making your truck feel quicker and more agile.
-
Enhanced Engine Sound: Many enthusiasts appreciate the throatier, more aggressive exhaust note produced by long tube headers. This is subjective, but it's a significant draw for many.
Drawbacks of Long Tube Headers on a 5.7 Hemi Ram 1500
While the performance gains are attractive, there are potential downsides to consider:
-
Cost: Long tube headers are a significant investment compared to other performance upgrades.
-
Installation Complexity: Installation can be challenging and may require professional assistance. The process often involves removing other components, and careful alignment is crucial.
-
Emissions: Long tube headers can impact emissions, potentially causing your truck to fail emissions testing in some areas. This is especially true if you don't have a properly tuned ECU.
-
Ground Clearance: The extended length might reduce ground clearance, posing a risk of damage when driving off-road or over uneven surfaces.
-
Check Engine Light: In some cases, installation may trigger a check engine light due to changes in exhaust flow and oxygen sensor readings. A professional tune is usually recommended to address this.
Will Long Tube Headers Void My Warranty?
Installing aftermarket long tube headers almost certainly will void your powertrain warranty. Consult your vehicle's warranty documentation and your dealership to understand the implications before proceeding with the modification.
What are the Different Types of Long Tube Headers?
Several variations exist, each with unique characteristics:
-
Material: Stainless steel is the most common material due to its durability and corrosion resistance. Ceramic coating is an option for added heat protection and improved appearance.
-
Tube Diameter: The diameter of the header tubes impacts exhaust flow. Larger diameter tubes generally lead to better flow at higher RPMs.
-
Collector Design: The collector is where the individual header tubes merge. Different designs (e.g., 3-into-1, 4-into-1) influence exhaust flow and can impact performance.
Do I Need a Tune with Long Tube Headers?
Yes, it's highly recommended to get a custom tune after installing long tube headers. A tune adjusts the engine's computer to optimize fuel delivery and ignition timing to match the improved exhaust flow. This ensures optimal performance, prevents potential issues, and helps to avoid a check engine light.
How Much Horsepower Will I Gain?
The horsepower gains vary depending on the specific header design, the rest of your engine modifications, and your vehicle's condition. Generally, expect gains in the 15-30 horsepower range, possibly more with additional supporting mods.
Conclusion
Long tube headers offer a substantial performance upgrade for the 5.7 Hemi Ram 1500, delivering noticeable increases in horsepower and torque. However, it's essential to carefully weigh the benefits against the potential drawbacks, including cost, installation complexity, and potential warranty implications. Thorough research and professional installation are crucial for a successful and rewarding outcome. Remember to consult with a qualified automotive professional for advice tailored to your specific vehicle and driving needs.
