Installed Carven Progressive a few days ago and have to say, I love the sound of my Ram now! I'm glad that I didn't go with the Competitor as the Progressive is plenty loud - I feel like I would be obnoxious with anything louder.
I do have to say though, the drone at 1500rpm is almost unbearable. I took my first trip out of the city limits the other day and traveling at 70mph almost caused me to lose my mind. Otherwise, there is no drone at any other rpm which is excellent for most of my driving.
The only time I've experienced the helicopter sounds with MDS is when driving in 4/5 gear around town. I kick it off, and everything goes back to sounding great. MDS at higher speeds doesn't affect the sound/drone as best I can tell.
Overall, I love the choice and would do it again - but I'd sure like to get rid of that excessive drone at 1500rpm without having to cut my pipe to apply the J pipe fix.
