This system retains MDS & the Active Exhaust Valve Feature
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.
The Power of Music
When the right notes are played together on a pipe organ, an ethereal effect is created with dramatically more acoustical depth and texture than a single note. The mathematical formula that determines the dimensions of pipes forming these harmonically-pleasing chords originated with Pythagoras, and has been adapted by Borla for exhaust applications. The exciting result is the Borla Polyphonic Exhaust Harmonizer, which is now featured in select Borla exhaust systems.
These patent-pending units contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound to the Borla mufflers. The mufflers then enhance this tone to the character and volume appropriate for our Touring, S-Type and ATAK® systems. The straight-through design of Polyphonic Harmonizers ensures zero performance loss.
