With the MagnaFlow Nissan Frontier Street Series Cat-Back Performance Exhaust System #19574 everyone else will know who rules the road once they hear that deep resonant exhaust note that MagnaFlow is famous for. Exhaust kit #19574 features 3” main piping that passes through a straight-through muffler before terminating in a 4” single side exit with polished tip. An integrated NDT (No Drone Technology) resonator and versatile tuning of the piping and straight-through muffler ensure that this exhaust system nullifies the unwanted droning noises that can otherwise occur at freeway speeds while maintaining moderate exterior and mild interior sound levels. The exhaust system is designed to enhance your 2022-2025 Nissan Frontier Crew Cab or King Cab with dyno-proven performance gains and tuned to produce mild interior and moderate exterior sound levels. This Nissan Frontier exhaust system is produced using CNC precision robotic manufacturing techniques and durable corrosion resistant stainless steel. #19574 is backed by MagnaFlowâ€s limited lifetime warranty.
