Product details
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.
