The 5.7L Hemi engine is a powerhouse, but unleashing its full potential often requires strategic modifications. One popular upgrade among performance enthusiasts is installing long tube headers, and JBA is a frequently considered brand. This guide dives deep into JBA long tube headers specifically designed for the 5.7 Hemi, exploring their benefits, drawbacks, and considerations before purchase and installation.
What are JBA Long Tube Headers?
JBA (JBA Performance) manufactures high-quality exhaust headers for various vehicles, including those equipped with the 5.7L Hemi engine. Their long tube headers are designed to significantly improve engine performance by optimizing exhaust flow. Unlike shorty headers, which have shorter primary tubes, long tube headers extend further down the chassis, providing a less restrictive path for exhaust gases. This improved flow translates to increased horsepower and torque, particularly in the mid-to-upper RPM range.
Benefits of JBA Long Tube Headers for 5.7 Hemi
-
Increased Horsepower and Torque: The primary advantage is a noticeable gain in both horsepower and torque. The less restrictive exhaust path allows the engine to breathe more efficiently, leading to substantial performance increases. The exact gains vary based on other modifications and vehicle specifics, but significant improvements are common.
-
Improved Engine Efficiency: By optimizing exhaust scavenging, long tube headers contribute to more efficient engine combustion. This can lead to improved fuel economy, although the effect might be less noticeable than the performance gains.
-
Enhanced Engine Sound: Long tube headers often produce a deeper, more aggressive exhaust note, enhancing the overall driving experience for many enthusiasts.
-
High-Quality Construction: JBA is known for building durable and well-constructed headers, using materials designed to withstand the high temperatures and pressures of the exhaust system.
Drawbacks of JBA Long Tube Headers for 5.7 Hemi
-
Potential for Emissions Issues: Long tube headers can potentially affect emissions compliance, particularly if not paired with a properly tuned engine management system. In some regions, this could lead to failure of emissions testing.
-
Installation Complexity: Installation typically requires more time and effort than installing shorty headers. It may necessitate removing other components and possibly require specialized tools. Professional installation is often recommended.
-
Increased Exhaust Drone: The enhanced exhaust note, while desirable to some, can also lead to increased exhaust drone at certain RPM ranges, particularly during highway driving. This is a subjective factor, and some drivers might find it bothersome.
-
Ground Clearance Issues: The extended length of the headers might lower ground clearance, potentially leading to scraping on uneven surfaces or steep driveways. This is dependent on the specific vehicle and its suspension setup.
What are the Different JBA Long Tube Header Options for the 5.7 Hemi?
JBA offers several header options for 5.7 Hemi engines, often varying by year, model, and specific engine configuration (e.g., different variations of the 5.7 Hemi exist across different Chrysler, Dodge, and Ram vehicles). Checking JBA's website or contacting a retailer specializing in JBA products is crucial to identify the correct headers for your particular vehicle. Header part numbers are specific to each application, so double-checking compatibility is paramount.
Do I Need a Tune with JBA Long Tube Headers?
Yes, it's strongly recommended to get a professional engine tune after installing JBA long tube headers. The significant change in exhaust flow can cause the engine to run lean, potentially leading to damage if not properly adjusted. A custom tune optimizes the air/fuel mixture and ignition timing to take full advantage of the performance gains offered by the headers, while also ensuring safe and reliable operation.
How Much Do JBA Long Tube Headers Cost?
The price of JBA long tube headers varies depending on the specific application and retailer. It's best to check current prices directly from JBA or authorized retailers.
Are JBA Long Tube Headers Worth It?
The decision of whether JBA long tube headers are "worth it" is subjective and depends on individual priorities and budget. If you're seeking significant performance gains and are prepared for the potential drawbacks (installation complexity, potential emissions issues, and cost), then they can be a worthwhile investment. However, if you're looking for a simple bolt-on modification with minimal impact on other systems, shorty headers might be a more suitable option. Carefully weigh the pros and cons before making your decision.
