How to Install Ram 1500 5.7 Hemi Shorty Header: A Step-by-Step Overview

Installing aftermarket headers is one of the most effective ways to improve exhaust flow, enhance throttle response, and increase overall horsepower in performance vehicles. This article provides a comprehensive, step-by-step overview of installing DynoVox shorty headers on a fourth-generation HEMI-powered Ram truck. The content is based on a complete installation performed by a well-known automotive content creator in the performance truck community. Drawing from his detailed video, this guide not only highlights the key stages of the installation process but also offers valuable insights into common challenges, practical workarounds, and technical considerations.

Whether you are preparing for your own header upgrade or simply researching performance modifications, this article offers real-world experience and expert-level tips to help ensure your project is a success.

Introduction to the DynoVox 5.7 Hemi Shorty Headers

DynoVox provided a set of high-quality shorty headers specifically designed for the HEMI Ram. The headers arrived with new gaskets and hardware, and feature a polished, performance-ready appearance. The driver-side header features an angled-down design, while the passenger side offers a straight shot layout, both engineered for better exhaust flow.

Preparing for the Installation

Before beginning the installation, several key components needed to be removed or repositioned:

Steering Shaft Bolt

Dipstick Bolt

Heat Shield

Steering Extension (due to the presence of a 3-inch body lift)

The installer had previously replaced broken manifold studs, making the removal process smoother. The body lift provided valuable additional clearance, especially on the passenger side, which had minimal obstructions.

Passenger Side Header Installation

With the wheel on, the installer carefully accessed the bolts and removed the heat shield and associated components. Thanks to the body lift, there was ample room for maneuvering. The passenger side proved relatively straightforward:

The factory manifold was removed without broken studs.

The new header was positioned and hand-threaded using the supplied gasket.

A steering extension was reinstalled after header fitment.

Final torquing required patience due to tight bolt access underneath.

Driver Side Header Installation

The driver's side proved more challenging due to tighter clearances and bulkier steering components:

The header had to be inserted at a specific angle and partially installed before being fitted to the engine.

The steering shaft posed clearance issues, even with the body lift.

Engine mounts were removed, and the engine was carefully supported and lifted to allow proper alignment and installation.

Slight denting of the header tubing was required to clear tight spots near the steering shaft.

Despite these complexities, the header was successfully installed, aligned with the block, and all upper bolts were torqued down. The installer noted that the lower bolts were more tedious due to limited wrench access.

Additional Modifications for Clearance

To create additional room for bolt access and proper fitment:

The starter motor was temporarily removed with just two bolts, providing excellent lower-side access.

A sensor was also disconnected for clearance and later reinstalled.

A specific cover under the truck, which had been previously dented, was removed permanently.

Exhaust System and Y-Pipe Fitment

After both headers were installed, attention turned to reconnecting the exhaust system:

The Y-pipe was aligned and bolted into place.

A short bolt was used on the bottom flange to ensure it did not interfere with the exhaust piping.

The installer used stubby wrenches and stubby ratchets—essential tools for tight spaces—to tighten the Y-pipe bolts securely.

Final Checks and Engine Start-Up

Once everything was tightened and all mounts and components were reinstalled:

The engine was started for a test.

The exhaust tone remained fairly similar to stock but slightly deeper and more refined.

No leaks or clearance issues were observed.

The truck was now fully operational with the new DynoVox shorty headers installed, completing the performance upgrade.

Reflections on the Installation Process

The installer acknowledged that the process was far more complex than expected, especially for a first-time header installation. Even with a body lift, tight clearances required significant time, effort, and creativity. Some valuable lessons and tips emerged from the experience:

Use stubby wrenches and ratchets to access tight bolts.

Expect modifications to steering components and engine mounts, especially on early fourth-gen Rams.

Allow extra time and be prepared for trial-and-error when aligning the headers.

Replace any broken or rusted studs before starting to avoid setbacks.

Despite the difficulty, the final result was visually impressive, with the new headers adding a polished, high-performance look under the hood.

Conclusion

Installing DynoVox shorty headers on a HEMI Ram can be a rewarding but demanding project. While the headers are well-designed and fit as intended, the limited space around the engine bay presents challenges that require mechanical know-how and patience. This installation serves as both a performance upgrade and a valuable learning experience for any hands-on truck owner. For those planning a similar upgrade, adequate preparation, quality tools, and careful attention to detail are key to success.
