I did cat back with flow master 50 series suv W/3". its not that bad as unless you in it you don't hear alot. I can't answer about the mds part, mine is turned off. Once it stops raining up here I will do some sound clips

You removed the resonator when you did the catback?

[pjmjr508]

Any drone while cruising on the highway?

Ive got the flowmaster 50 muffler only, its then welded to the stock rear piece. Its loud when are you WOT, has a small drone on the highway but not annoying and you can hear when the MDS come on. I like the sound it makes not to much but I will be doing a straight pipe from muffler cause I want it to be loud. Keep in mind I have the intake on, before it wasnt as loud as it is now. Honestly if you arent on the throttle much like I am you wont notice to much of a difference.

The fellow that installed my new muffler yesterday suggested trying it with the resonator still in place and then deleting the resonator if I wanted it louder. I just had it do both while it was on the lift. If you are worried about drone then you might do it in steps. The stock muffler is huge. You will save the weight of a kid by replacing it with a Flowmaster like I did or a similar smaller muffler.
