Specially engineered, interchangeable components equipped with race bred V-Band clamps allow you to easily switch from MagnaFlow’s aggressive exhaust note with the xMOD Muffler Module to the wild sounds offered by the xMOD xTreme Deletes. PLEASE NOTE: While xMOD systems are 100% emissions legal, the use of xTreme Deletes is recommended for track use only. Check local noise regulations for street legality. Unique to this system, the xMOD Series for the WRX is the very first to feature a dual resonator No Drone Technology (NDT) setup. Tuned to passively cancel out two of the different sound frequencies that can create low, exasperated drone, we are able to maintain the distinctive note of the Boxer motor while drastically improving the in-cabin experience regardless of the system’s configuration. xMOD for the Subaru WRX: get the sound you want, when you want it.
