Multi-Displacement System (MDS) valves deactivate 4 of the 8 lifters in a (V8) cylinder system when the throttle is closed or in cruise mode at low RPM. The purpose of this feature is to enhance the fuel economy available to the HEMI engines introduced by Chrysler. ALL Mopar models 2005+ are factory equipped with the MDS mode UNLESS you have a Challenger with a factory MANUAL transmission OR you have custom tuned your vehicle to eliminate the factory MDS feature. Please do not confuse MDS with Active Exhaust Valves (AEV). The purpose of AEV is to modify the decibel level (sound) of the exhaust system. If one has a goal to increase the duration of AEV this can be achieved by tuning the PCM to manually control between Default, Sport & Track mode.

No Drone Exhaust Technology CORSA Performance entered the exhaust category in 1998, re-writing the rulebook for what a performance exhaust should be with the launch of our revolutionaryRSC® (Reflective Sound Cancellation®) Technology. RSC®TechnologyallowsCORSAPerformance the unique ability to selectively target and eliminate resonant frequencies that cause drone, by reflecting sound waves out of phase, while custom tuning the exhaust note. Since the debut ofRSC® Technologyin 1998 on the C5 Corvette, CORSA Performance has invested countless resources developing proprietary tools used in Perfecting the Science of Sound, resulting in world-wide recognition for high-performance, aggressive exhausts systems that eliminate drone.
Today CORSA Performance employs multiple forms of proprietaryRSC Technologiesand acoustic solutions to cancel resonant frequencies that cause drone and produce the desired exhaust tone. Every CORSA Performance exhaust system manufactured takes into account OEM design, desired performance output as well as interactions of the entire Exhaust System. During the development phase anRSC Technologyis chosen that best attains the desired balance of acoustics resulting in hundreds of unique designs that cover our numerous vehicle applications. Rarely are any two Exhaust Systems featuringRSC Technologythe same.
1. No Drone Unwanted, low frequency sound waves are diverted using specific geometry and are reversed 180 degrees out of phase.
2. Point of Cancellation Our patented sound technology is engineered to target and eliminate unwanted frequencies that cause drone.
3. Performance Sound Acoustic tuning creates an aggressive sound under acceleration that is styled to match the personality of your vehicle.
4. Maximized HP and TQ A straight-through, unrestricted design reduces back pressure; increasing engine efficiency, horse power and torque.
