The best of both worlds. Jekyll and Hyde. These are perhaps the best ways to describe versatility offered by the NDT Delete Module. Our engineers designed this configuration to create an aggressive, throaty exhaust sound under acceleration while maintaining a more stock-like tone under highway driving conditions. This is all made possible with MagnaFlow’s No Drone Technology, or NDT, which is our solution to the unwanted in-cabin noise that can sometimes occur in car with a high-performance exhaust system. By using ¼-wave passive noise cancellation tuned to the acoustic frequency range that causes drone in the TRX, the NDT resonators ensure this xMOD system delivers the highest level of performance with a comfortable interior sound.
