The 5.7L Hemi in your Ram 1500 is a powerful engine, but there's always room for improvement. One popular modification for boosting horsepower and torque is installing long tube headers. These aren't just bolt-on parts; they represent a significant upgrade that impacts your truck's performance and sound. This guide dives deep into long tube headers for the 5.7 Hemi Ram 1500, exploring their benefits, drawbacks, and what you should consider before making the investment.
What are Long Tube Headers?
Long tube headers are exhaust manifolds that feature longer primary tubes compared to shorty headers or the stock manifolds. These longer tubes allow exhaust gases to flow more efficiently, reducing back pressure and improving engine breathing. This improved scavenging effect translates directly into increased horsepower and torque, particularly in the mid-to-upper RPM range.
Benefits of Long Tube Headers on a 5.7 Hemi Ram 1500
-
Increased Horsepower and Torque: This is the primary reason most owners opt for long tube headers. The improved exhaust flow leads to noticeable gains, typically ranging from 15-30 horsepower and a similar increase in torque, depending on other modifications.
-
Improved Engine Response: With less restriction on the exhaust flow, the engine responds more quickly to throttle inputs, resulting in a more spirited driving experience.
-
Enhanced Exhaust Note: Long tube headers usually produce a more aggressive and throatier exhaust note, a desirable characteristic for many truck owners. This is partly due to the longer tube lengths and the often-accompanying cat-back exhaust system upgrades.
-
Increased Engine Efficiency: By improving scavenging, long tube headers can also contribute to slightly improved fuel economy, though this benefit is often overshadowed by the increased power output and the driver's tendency to use that extra power!
Drawbacks of Long Tube Headers
-
Installation Complexity: Installing long tube headers can be a challenging DIY project. It often requires specialized tools and a significant amount of time and patience. Professional installation is often recommended.
-
Potential for Check Engine Light: Depending on the specific header design and your truck's emission system, long tube headers may trigger a check engine light due to changes in the oxygen sensor readings. Wideband O2 sensors and tuning can help mitigate this.
-
Ground Clearance Issues: The longer primary tubes might reduce ground clearance, particularly when navigating rough terrain or steep inclines.
-
Cost: Long tube headers are a relatively expensive modification compared to other performance upgrades.
-
Emissions Compliance: In some regions, installing long tube headers may not comply with emission regulations. This is a crucial point to check before purchase and installation.
What are the Different Types of Long Tube Headers?
Several long tube header designs cater to the 5.7 Hemi Ram 1500. They vary based on materials (stainless steel is the most common), tube diameter, collector design, and the presence of catalytic converters. Some headers come with high-flow catalytic converters, while others require separate installation. Choosing the right type depends on your budget, performance goals, and emission regulations.
How Much Horsepower Can I Expect to Gain?
The horsepower gains from long tube headers vary based on several factors: the specific header design, the rest of your engine's modifications (intake, exhaust, tuning), and even the altitude where you live. Generally, you can expect gains in the 15-30 horsepower range, along with a similar increase in torque. However, more significant gains are possible with supporting modifications.
Do I Need a Tune After Installing Long Tube Headers?
It's highly recommended to get a professional tune after installing long tube headers. The altered exhaust flow significantly impacts the air-fuel mixture, and a tune optimizes the engine's parameters for the new setup, maximizing performance and preventing potential engine damage. A tune also helps prevent or address any check engine light issues that might arise.
Are Long Tube Headers Street Legal?
The legality of long tube headers depends on your location and emission regulations. Some areas strictly enforce emission standards, making aftermarket headers without integrated catalytic converters illegal. Always check your local laws and regulations before purchasing and installing long tube headers.
Conclusion
Long tube headers offer a significant performance upgrade for the 5.7 Hemi Ram 1500, delivering noticeable gains in horsepower and torque, improved throttle response, and a more aggressive exhaust note. However, it's crucial to weigh the potential drawbacks, including installation complexity, cost, and potential emission compliance issues. Thorough research, careful planning, and professional installation are key to reaping the rewards of this popular modification. Remember to check local laws and regulations before proceeding.
