Construction & Design

Crafted from premium 304 stainless steel, the Injen Muffler Delete Pipe offers exceptional resistance to rust, cracking, and corrosion compared to standard steel exhaust components. The mandrel bent tubing maintains a consistent 60mm diameter throughout, ensuring smooth airflow and minimizing exhaust restrictions. This precision engineering enhances engine efficiency and durability, even in demanding off-road environments.

The kit retains all factory hanger locations for a secure, vibration-free fitment that requires no modifications to your Jeep’s exhaust system. This robust construction guarantees long-lasting performance and reliability on and off the trail.

Performance & Sound

By removing the factory muffler, this kit reduces exhaust backpressure, allowing your Jeep’s V6 engine to breathe more freely. The result is improved throttle response and a noticeable increase in exhaust volume. The exhaust note becomes deeper and more aggressive, providing a commanding presence that enhances the driving experience both on pavement and rugged terrain. The enhanced sound profile is especially prominent under full throttle, giving your Wrangler a distinctive and sporty tone.

Installation & Fitment

The Injen Muffler Delete Pipe is designed for a straightforward, bolt-on installation using existing factory mounting points. No cutting, welding, or additional modifications are necessary, making it accessible for both DIY enthusiasts and professional installers. Installation typically takes less than 20 minutes, allowing you to easily switch between the muffler delete and the original muffler depending on your driving preferences.
