The MagnaFlow Ram TRX xMOD Cat-Back Performance Exhaust System #19552 provides your already powerful 2021 Ram 1500 TRX with the versatile, configurable exhaust sound that the xMOD Series is known for. Each #19552 exhaust kit utilizes MagnaFlow’s No Drone Technology (NDT) to keep unwanted noises under control at lower RPMs while delivering MagnaFlow’s deep, signature exhaust tone in any configuration. The best example of NDT can be found in the exhaust kit’s swappable NDT Delete module, which utilizes ¼-wave passive noise cancellation to allow for relaxed highway driving while enabling the pipes to really open up and roar under acceleration. Two more interchangeable xMOD modules are included in this exhaust kit, namely the xTreme Deletes and Muffler Modules. The former enables a straight pipe, unmuffled and shouty exhaust sound, while the latter provides a deep and powerful, yet more tame tone thanks to MagnaFlow’s tried-and-true straight-through muffler design. Each of these modules has been engineered to deliver dyno-proven performance and can be easily swapped in and out at your whim thanks to the use of racing-bred v-band clamps. This Ram 1500 TRX exhaust system #19552 features mandrel bent 3” tubing that flows to a dual exit configuration featuring black double-wall powder coated 5” tips. The entire kit is produced using CNC precision robotic manufacturing and features durable, 100% stainless steel construction backed by MagnaFlow’s limited lifetime warranty.
