The 5.7L Hemi in your Ram 1500 is a powerful engine, but there's always room for improvement. One popular modification to boost horsepower and torque is installing long tube headers. These aren't a simple bolt-on, however, and understanding the pros, cons, and considerations is crucial before taking the plunge. This guide dives deep into 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 stock manifolds. These longer tubes allow exhaust gases to flow more efficiently, reducing backpressure and increasing scavenging (the process of pulling spent exhaust gases from the cylinders). This improved flow translates directly into increased horsepower and torque, particularly in the mid-to-upper RPM range.
Why Choose Long Tube Headers for Your 5.7 Hemi Ram 1500?
The primary benefit is a noticeable performance gain. You'll experience improved throttle response, a more aggressive exhaust note, and a significant increase in horsepower and torque. The exact gains vary depending on other modifications, but you can generally expect a substantial bump in power.
What are the Drawbacks of Long Tube Headers?
While the performance benefits are significant, there are drawbacks to consider:
- Increased drone: Long tube headers often produce a louder, more pronounced exhaust drone at cruising speeds. This can be irritating on long drives.
- Potential for check engine light: Depending on the header design and your vehicle's configuration, you might trigger a check engine light due to altered oxygen sensor readings. An aftermarket tune can often resolve this.
- Installation complexity: Installing long tube headers usually requires more time and effort than installing other performance parts. You may need professional installation.
- Cost: Long tube headers are a relatively expensive modification.
- Emissions: In some areas, modifications that significantly alter emissions could lead to failed emissions testing.
What are the Different Types of Long Tube Headers Available?
Several header designs cater to various needs and budgets. Some are made from stainless steel for durability, others from less expensive materials. Some are coated to resist heat and corrosion. Researching different brands and materials will help you choose the best option for your specific requirements and budget. Consider factors like material, coating, flange design, and primary tube diameter.
Will Long Tube Headers Void My Warranty?
This is a crucial question. Modifying your vehicle's exhaust system can potentially void your manufacturer's warranty, especially if the modification causes damage to other components. Check your warranty documentation carefully, and consider the potential risks before proceeding. It's often advisable to discuss modifications with your dealership beforehand.
Do I Need a Tune with Long Tube Headers?
While not always strictly necessary, a custom tune is highly recommended. A tune optimizes the engine's computer settings to work effectively with the increased exhaust flow provided by the headers. This maximizes power gains and prevents potential issues like a check engine light or running lean.
How Much Horsepower Can I Expect to Gain?
The horsepower gains vary considerably, depending on the other modifications made to your truck. Estimates range from 20-50 horsepower, but achieving the higher end of that range often requires additional modifications, such as a cold air intake, upgraded exhaust system, and a custom tune.
What is the Best Brand of Long Tube Headers for a 5.7 Hemi Ram 1500?
There's no single "best" brand. Reputable manufacturers offer high-quality headers, and the best choice often comes down to budget, desired features (like coating), and reviews from other Ram owners. Research different brands and read user reviews before making a decision.
Are Long Tube Headers Street Legal?
Legality depends on your local regulations. Some regions have stricter emissions standards than others. It is your responsibility to ensure that any modification you make complies with all applicable laws and regulations.
This guide provides a comprehensive overview of long tube headers for your 5.7 Hemi Ram 1500. Remember to always research thoroughly, consider all aspects, and perhaps consult with a professional mechanic before making any significant modifications to your vehicle. The power gains can be substantial, but careful planning and consideration are vital for a successful installation and optimal performance.
