The 5.7L Hemi engine in your Ram 1500 is a powerhouse, but are you getting everything it can offer? Long tube headers are a popular modification for unlocking significant horsepower and torque gains. This comprehensive guide dives deep into the world of long tube headers for your 5.7 Hemi Ram 1500, addressing common questions and concerns.
What are Long Tube Headers?
Long tube headers are exhaust manifolds that feature longer primary tubes compared to stock or shorty headers. These longer tubes allow for a more efficient scavenging effect, improving exhaust gas flow and reducing back pressure. This enhanced exhaust flow translates directly into increased horsepower and torque, particularly in the mid-to-upper RPM range. The increased scavenging effect also improves the engine's breathing, allowing for better combustion.
Why Choose Long Tube Headers for my 5.7 Hemi Ram 1500?
The primary benefit of installing long tube headers is a noticeable increase in horsepower and torque. Expect gains ranging from 20-40 horsepower and a similar increase in torque, depending on the specific header design, accompanying modifications (like a tune), and the condition of your engine. This improvement is particularly noticeable during acceleration and at higher RPMs. Besides power gains, long tube headers can contribute to a more aggressive exhaust note, enhancing the overall driving experience.
Will Long Tube Headers Impact My Truck's Driveability?
This is a frequently asked question, and the answer is nuanced. While long tube headers generally improve performance, some potential downsides exist. You might experience a slight decrease in low-end torque, making initial acceleration feel slightly less responsive at very low RPMs. However, this is often overshadowed by the significant gains in mid-range and high-end power. Additionally, some users report an increase in drone at certain RPM ranges. A properly designed and installed system should minimize this. Ultimately, the increased power often outweighs the minor trade-offs for many enthusiasts.
What are the Different Types of Long Tube Headers Available?
The market offers a variety of long tube headers, each with its own features and specifications. They differ primarily in materials (stainless steel being the most common for durability), tube diameter, primary tube length, and collector design. Choosing the right header will depend on your specific needs and goals. Some headers are designed for maximum power, while others prioritize smoother performance or a particular sound profile. Research different brands and read reviews before making a purchase.
Do I Need a Tune After Installing Long Tube Headers?
Yes, it's highly recommended to have your truck's computer retuned after installing long tube headers. The change in exhaust flow significantly alters the air/fuel ratio, potentially leading to poor performance or even engine damage if not corrected. A professional tune will optimize the air/fuel mixture to take full advantage of the improved exhaust flow from the headers, maximizing the power gains and ensuring smooth, safe operation.
Are Long Tube Headers Street Legal?
This is dependent on your location and local emissions regulations. Some areas have stricter emission standards that might prohibit the use of aftermarket long tube headers. Check with your local Department of Motor Vehicles (DMV) or equivalent agency to ensure compliance before installation. Additionally, some headers might require modifications to accommodate the use of catalytic converters to meet emission standards.
How Much do Long Tube Headers Cost for a 5.7 Hemi Ram 1500?
Prices vary significantly depending on the brand, materials used, and additional features. You can expect to pay anywhere from a few hundred dollars to well over a thousand dollars for a set of high-quality long tube headers. The investment is worthwhile if you're looking for a substantial performance upgrade, but it's essential to factor the cost of installation and a potential tune into your budget.
What About Installation? Is it Difficult?
Installing long tube headers is generally considered an advanced modification, requiring mechanical skills and experience. The process involves removing the factory exhaust manifolds, installing the new headers, and potentially modifying or replacing the exhaust system components. This often requires specialized tools and knowledge. It's often best to have a professional mechanic perform the installation to avoid damage to your truck or engine.
This detailed guide provides a solid foundation for understanding long tube headers and their potential impact on your 5.7 Hemi Ram 1500. Remember to always conduct thorough research and consult with professionals before making any modifications to your vehicle.
