ROCK BASHER 3 IN 304 Stainless Steel Cat-Back Exhaust System
The ROCK BASHER Cat-Back Exhaust System is purpose-built for the 2021–2025 Jeep Wrangler JL Rubicon 392 6.4L HEMI, delivering maximum durability, aggressive sound, and superior off-road protection. Designed for serious trail use, this system eliminates vulnerable rear exit tips while providing unrestrictive exhaust flow and a bold V8 exhaust note.
Constructed from 3-inch mandrel-bent 304 stainless steel tubing, the ROCK BASHER system ensures optimal exhaust flow, improved throttle response, and exceptional corrosion resistance. A free-flowing stainless steel muffler with an internal X-pipe absorbs high-frequency tones while producing a powerful, aggressive exhaust sound that unleashes available horsepower and torque.
For off-road reliability, the system features a unique pre-axle turn-down exhaust outlet, routing exhaust gases under the vehicle before the rear axle. This design significantly reduces the risk of exhaust damage when navigating rocks, ledges, and steep terrain—no smashed or lost exhaust tips to worry about.
Installation is straightforward using factory mounting locations, OE-style hangers, and high-quality stainless steel band clamps to ensure a secure, leak-free fit. The system is 100% MIG-welded for long-term strength and durability under extreme heat and vibration.
Please note that this exhaust eliminates factory exhaust valves, removing the ability to switch between factory sound modes in favor of a consistent, performance-focused tone.
Proudly engineered and manufactured in Corona, California, the ROCK BASHER Cat-Back Exhaust System is the ultimate solution for Rubicon 392 owners who demand rugged performance and trail-ready design.
