Cat-Back

The BORLA® team has created a system especially for the 6.4L Wrangler Rubicon 392 and Moab 392. This Cat-Back™ system contains BORLA®'S patented SwitchFire® technology which eliminates the turbulent center intersection of a standard X-Pipe. The SwitchFire® design truly blends the combustion pulses from both sides of the engine for improved performance and a custom sound. The system is engineered for performance and has our classic S-Type sound delivers which delivers an aggressive, yet balanced sound with a deep tone and no drone. This exhaust system features a 2.75" inlet that flows into 3" pipes and exits via dual 4" round polished T-304 stainless steel exhaust tips on each side. A system with a black coated muffler assembly and tips is also available. The system features Dual-Mode valves so you can customize the sound of your vehicle. T-304 stainless steel construction of the system provides additional durability over the stock exhaust. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Give your Bronco a boost in performance and sound, bolt on a BORLA®. All BORLA® Cat-Back™ and Axle-Back systems are made in the USA and are covered by our Million-Mile warranty.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.

Note regarding Rubicon badged vehicles.

Rubicon badging/decals alone do not confirm Rubicon specification, as some vehicles may have aftermarket or dealer-added decals. Please confirm your vehicle’s VIN/trim and Rubicon-specific hardware before ordering, especially for suspension, steering, axle, driveline, bumper and underbody parts.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.
