Borla 140893CB ATAK Cat-Back Exhaust System for 2021-2026 Jeep Wrangler Rubicon 392 and 2026 Moab 392 6.4L V8

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 aggressive ATAK® sound. It provides a more exciting driving experience without any drone. This exhaust system features a 2.75" inlet that flows into 3" pipes and exits via dual 4" round black coated T-304 stainless steel exhaust tips on each side. The entire muffler assembly is coated black with high temperature finish. An uncoated system with polished T-304 stainless steel 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.

Upgrade the sound, flow, and durability of your compatible Jeep Wrangler with the Borla 140893CB ATAK Cat-Back Exhaust System. Engineered specifically for 6.4L V8 Wrangler Rubicon 392 models and the 2026 Wrangler Moab 392, this performance exhaust system delivers Borla’s aggressive ATAK sound while minimizing unwanted interior drone. Its dual-mode valves allow you to customize the exhaust character for different driving conditions.

The system incorporates Borla SwitchFire technology, which replaces the turbulent center intersection found in a conventional X-pipe with a design that blends combustion pulses from both sides of the engine. This supports smooth exhaust flow, responsive performance, and a distinctive sound. The 2.75-inch inlet transitions into a 3-inch mandrel-bent exhaust system and exits through dual 4-inch round black-coated T-304 stainless steel tips on each side. The muffler assembly features a high-temperature black coating for a durable, coordinated appearance.

Precision computer numerical control manufacturing and ultra-smooth mandrel bends help provide accurate fitment and efficient exhaust flow. T-304 stainless steel construction offers greater corrosion resistance and durability than the factory exhaust. Borla manufactures this Cat-Back system in the USA and backs it with the company’s Million-Mile Warranty. The system ships in two boxes. Professional installation is recommended. This product may require emissions-related acknowledgment where applicable; verify local regulations before installation.
