The system was first offered only on passenger cars, since the heavy demands of trucks would interfere with its operation. However, it was recalibrated for 2006 and was offered on all seven models, including SUV's and 1500 series trucks, using the 5.7 L engine.
In order to preserve the characteristic rumble of the V8 engines, Chrysler and Eberspaecher North America designed a special exhaust system for MDS-equipped vehicles. This includes FOUR SEPERATE mufflers, two large central ones for V8 mode and two smaller ones near the tailpipes for four-cylinder mode. Unlike the system used on Mercedes-Benz V12 engines, also designed by Eberspaecher, the system is mechanically passive. Most people that have an aftermarket exhaust didn't know they had four stock mufflers, that's the top first mod. Everyone gets a cat back exhaust and never even look under the truck first.
