Does anybody with a 5.7L MDS Challenger replaced their exhaust system with a Zoomer or other and then ran it on the highway when the MDS kicks in.
I am wondering how the 5.7L engine sounds since running on 4 cylinders an a custom exhaust system without resonators will probably not sound good.
TO BE TRUTHFUL, I CANNOT TELL WHEN THE MDS SYSTEM IS WORKING OR NOT.
THE OWNERS MANUAL SAYS THAT WHEN THE MDS KICKS IN, THE DISPLAY WILL SAY" FUEL SAVING" ABOVE THE AVERAGE MPG READING. I HAVE YET TO SEE THIS MESSAGE SHOW UP ON T HE DISPLAY.
HOW DO I KNOW WHETHER THE MDS SYSTEM IS EVEN WORKING????
THE MAGNAFLOW MUFFLERS SOUND SPECTACULAR WITH THIS ENGINE.
