i have not, but have heard several people say it does quiet down the truck. as a caution, i have also seen a few posts where these lines blow out. whiel i doubt its common it is a consideration. i would be apt to belive it has to do with corrosion or weakenin over time. or jsut flat out improper install.

I had one on my SD and it seemed to smooth the idle out some. Never noticed any other differences or the motor being quieter.

it just smoothed out my idle and it gives the pcm an acurate reading of both head pressures for better fuel demand i noticed a nice improvement for $50 bucks
