Re: 5.7 mds disable
i added a magnaflow muffler about 3 months ago and was getting this horrible exhaust note when i'd cruise at 40mph. you could hear the mds kicking on and off every few seconds. it was like it didn't know if it should be on or off. i bought the predator in december and disabled the mds. it completely eliminated that sound. i haven't noticed any decrease in mpg's either. i say disable it if you can.
