AFE 49-48077 MACH Force-Xp Mid-Pipe w/Resonator Delete for 18-24 Jeep Wrangler JL 3.6L V6. This system can be used with most aftermarket axle-back exhaust systems or with the factory tailpipe. 2-1/2" mandrel bent, 409 stainless steel tubing eliminates the primary resonator to increase flow and "turn-up" your exhaust tone with an improved sound.
