HEMI MDS questions

My 05 Magnum RT had the MDS, and it worked reasonably well, my only complaint was the added drone through the Magnaflow exhaust. Don't misunderstand me, my motor has the setup so it would have been nice to use it. If for some reason I didn't like it, I could always shut it off with the Diablo. I plan on driving my car to a number of shows in NY and PA, so why not take advantage of a system my motor already has. I would not spend a ton of money to get it, but if it worked, why not use it.....
