The 5.7L Hemi engine in your Ram 1500 is a powerhouse, but are you squeezing every ounce of potential from it? Long tube headers are a popular modification that can significantly boost horsepower and torque, delivering a more exhilarating driving experience. This comprehensive guide dives deep into the world of long tube headers for your 5.7 Hemi Ram 1500, addressing common questions and helping you make an informed decision.
What are Long Tube Headers?
Long tube headers are a performance upgrade that replaces your vehicle's stock exhaust manifolds. Unlike shorty headers, which are shorter and closer to the engine, long tube headers extend further down the chassis, typically exiting near or before the catalytic converters. This longer design allows for a more efficient scavenging effect, which means exhaust gases are expelled more effectively, improving engine breathing and performance.
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 improving exhaust flow, long tube headers allow the engine to breathe more efficiently, resulting in a noticeable increase in both horsepower and torque across the RPM range. You'll feel a more powerful and responsive engine.
- Improved Throttle Response: The improved scavenging effect translates to quicker throttle response, making the truck feel more agile and responsive.
- Enhanced Exhaust Note: Long tube headers typically produce a deeper, more aggressive exhaust note, adding to the overall performance feel.
What are the Downsides?
While long tube headers offer significant performance gains, it's crucial to acknowledge potential drawbacks:
- Potential for Increased Drone: The improved exhaust flow can sometimes lead to an increase in exhaust drone, especially at certain RPM ranges. This is a subjective experience and can vary depending on the header design and your exhaust system setup.
- Ground Clearance Issues: Because long tube headers extend further down, they might reduce ground clearance, potentially causing scraping on uneven surfaces or steep inclines. This is especially relevant for off-road use.
- Check Engine Light (CEL): Depending on your setup and location, installation of long tube headers might trigger a check engine light due to changes in the exhaust gas sensor readings. A proper tune is often recommended to address this issue.
- Installation Complexity: Installation can be more challenging compared to other modifications and may require professional installation.
What size headers should I get?
The optimal header tube diameter is usually dependent on several factors such as engine displacement, intended usage and modifications. Larger diameter tubes can lead to more low-end torque whereas smaller diameter tubes can yield higher horsepower at higher RPM. Consulting with experienced mechanics and researching header specifications before purchasing is highly recommended.
Do I need a tune after installing long tube headers?
A tune is highly recommended after installing long tube headers. The change in exhaust flow significantly impacts the air/fuel ratio and overall engine management. A custom tune optimizes the engine parameters to maximize the benefits of the headers and prevent potential damage. Without a tune, you may not see the full performance gains and could risk damaging your engine.
Are long tube headers legal?
The legality of long tube headers varies by region and often depends on emission regulations. Some areas might require modifications to meet emission standards or might outright ban them. Check your local regulations before purchasing and installing long tube headers.
What are some reputable brands of long tube headers for a 5.7 Hemi Ram 1500?
Several reputable brands offer long tube headers for the 5.7 Hemi Ram 1500. Researching reviews and comparing specifications from various brands will help you choose the best option based on your budget and performance goals. Remember to consider materials (stainless steel is preferred for longevity) and the header design’s compatibility with your specific Ram 1500 model and year.
Conclusion:
Long tube headers can dramatically improve the performance of your 5.7 Hemi Ram 1500, but they are not a plug-and-play modification. Careful consideration of the potential benefits, drawbacks, and legal implications is essential. Proper installation and a custom tune are highly recommended to unlock the full potential of this performance upgrade. Always consult with a professional mechanic if you have any doubts about the installation process or potential complications.
