The debate between aftermarket headers and stock exhaust systems has been ongoing among automotive enthusiasts, particularly for those who own a 2018 Ram with a 5.7 HEMI engine. In this article, we will delve into the differences between 5.7 HEMI headers and stock headers, focusing on power gains, sound improvements, and fuel efficiency.
Understanding Headers
Headers are an essential component of a vehicle’s exhaust system. They are designed to improve the flow of exhaust gases from the engine, which can lead to enhanced performance. The stock headers on the 2018 Ram are adequate for everyday driving, but aftermarket headers can offer significant advantages.
Power Gains with Aftermarket Headers
One of the primary reasons for upgrading to aftermarket headers is the potential for increased horsepower and torque. When comparing stock headers to aftermarket options, the following points should be considered:
- Aftermarket headers typically have larger diameter tubing, which reduces back pressure.
- They often feature smoother bends, improving exhaust flow.
- High-performance headers can be made from lightweight materials, further enhancing performance.
In testing, many owners have reported power gains ranging from 10 to 30 horsepower, depending on the specific headers and supporting modifications. This increase is often accompanied by improved throttle response and acceleration.
Sound Improvements
Sound is another critical factor for many enthusiasts. Upgrading to aftermarket headers can significantly change the exhaust note of the 2018 Ram. Here are some key points regarding sound improvements:
- Aftermarket headers can provide a deeper, more aggressive tone compared to stock headers.
- They often enhance the sound of the engine under load, making acceleration more exhilarating.
- Quality headers can reduce drone and unwanted noise at cruising speeds.
Many users report that the sound improvement is one of the most noticeable benefits of upgrading their headers, making their vehicle more enjoyable to drive.
Fuel Efficiency Considerations
While power gains and sound improvements are often the primary motivations for upgrading headers, fuel efficiency is another important aspect to consider. Here’s how aftermarket headers can impact fuel economy:
- Better exhaust flow can lead to improved engine efficiency, potentially resulting in better fuel mileage.
- Increased horsepower may allow for more efficient driving habits, as less throttle is needed to achieve desired speeds.
- However, aggressive driving to experience the enhanced sound and power can negate fuel efficiency gains.
Some drivers have reported modest improvements in fuel efficiency, particularly during highway driving. However, results can vary based on driving style and other modifications made to the vehicle.
Installation Considerations
Installing aftermarket headers on a 2018 Ram can be a complex process that may require professional assistance. Here are some points to consider regarding installation:
- Professional installation is recommended for those unfamiliar with exhaust systems.
- Some headers may require additional modifications, such as new gaskets or heat shields.
- Proper tuning may be necessary to maximize performance gains.
Ensuring a proper installation is crucial for achieving the best results from your new headers.
Conclusion
In summary, upgrading to aftermarket headers for a 2018 Ram with a 5.7 HEMI engine can provide notable power gains, sound improvements, and potential fuel efficiency benefits. While the stock headers are functional for everyday use, aftermarket options can enhance the overall driving experience. Enthusiasts should weigh the advantages against the cost and complexity of installation to determine what is best for their vehicle.
