STaSIS exhausts are designed to reduce back pressure for more power and efficiency. You’ll have a powerful tone at full throttle that stays refined during your commute so you can take care of business while enjoying your ride. T304 stainless steel exhaust systems work in harmony with the engine tuning software. The mufflers incorporate reflective and passive technologies to optimize sound and minimize back pressure, while maintaining low levels of cabin resonance at cruising speeds. Combined with tunable resonators, the sound is noticeably deeper and more aggressive without intruding in the cabin during normal driving conditions. Resonators and mufflers combine to give an exhaust tone that is perceptibly deeper and stronger with an aggressive throttle, without intrusive cabin noise at cruising speeds. For even more performance gains, combine an exhaust with STaSIS engine software. STaSIS engine software releases the full potential of your vehicle, providing reliable and smooth power increases without sacrificing day-to-day drivability. Our software replaces the factory software installed in the engine control unit (ECU), and is customized to adjust fuel delivery, boost settings, ignition timing, and other areas that will improve performance.
