Hey guys I have a 2012 Ram 1500 ST Regular Cab with the 5.7L Hemi 6 speed. I bought my truck used with 32k miles on it and it came with a K&N 63 Series Intake and a Flowmasters exhaust.
My question is, when I'm driving with the trans in the D position and not "manual shifting" my truck seems to make a loud "choking" sound or muffle sound from my K&N intake. The exhaust has a weird muffle/gargle to it aswell. But once I put the truck into the "manual shift" mode and I just drive with that in 6th gear, I dont get those noises. Is the noises the MDS system working? It only does it during real light throttle or if I'm in Drive and I'm doing like 35-45 and lightly hit the gas. It seems to do it when I'm in a higher gear and at a low RPM.
It has me concerned because it's something I've never heard on any other vehicle I've ever owned and I've owned all kinds of turbo and non turbo cars with intakes and exhausts.
It almost sounds like my intake is choking and my exhaust is, in a sense, choking aswell. I can't tell if it's the MDS doing this or what.
