I don't understand why every one is truing off MDS? Are you haveing problems with it? My 06 is about to turn off 100K miles and I'm inlove with my MDS. 21mpg on the highway.
What are the advantages of turning it off? Besides getting bad gas mileage?
many members here have reported that leaving the stock resonators on with an aftermarket muffler eliminates the drone.I have an MBRP cat back system and with MDS its sounds atrocious on the highway when it kicks in. The drone is enough for me to want to go back to stock. Worst mod I ever made. Now I know I can shut it off with a powerchip or Diablo but I should have just stayed stock in the first place and saved the $$.
I should say that any other time without MDS the system sounds good, if not loud but I work 3rd shift and I can't idle my truck in the driveway with the remote start without being an a$$hole to the neighbors.
