The BORLA(r) team has created a system especially for the 6.4L Wrangler Rubicon 392. This Cat-Back(tm) system contains BORLA(r)'S patented SwitchFire(tm) technology which elimiantes the turbulent center intersection of a standard X-Pipe. The SwitchFire(tm) 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 ATAK(r) sound, which is our most aggressive 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 exists via dual 4" polished T-304 stainless steel exhaust tips on each side. 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.
