Hey everyone new to the forum i just bought a 2006 dodge ram 1500 5.7 hemi and i had a garage put on a new exaust they cut out the original muffler an one resinator and installed a FLOWMASTER 44 SERIES mufller with duals off that going out the back i have read some forums and see some people have the same problem when at low rpm going into over drive it makes a drone like or loud humming noise some say it's the MDS kicking in my question is how do i get rid of it but still keep the duals and nice sound is there another muffler i can replace it with to fix it or should i just go back to the stock exhaust? It's to bad because it sounds really nice untill it kicks in to OD thank for any help.

 

possibly puting the resonator back on? i know it sucks but it keeps the drone down inside the cab

 

if you get this you can turn off the MDS

get a programmer that allows mds delete.... mds sucks especially with exhaust system. my 40 series drones as is but not like the annoying mds drone.

 

Just drive it in tow/haul mode. This disables the MDS.

 

thanks for the info i'm going to buy a programmer the PREDATOR sounds like a good choice.

 

Yeah, the Diablo and Superchips units both allow you to turn off MDS. Gains are fairly the same from what I understand too.

 

What the heck is a drone anyway?

 

Thats the noise these guy make when they screw up the car or truck

 

It's a really bad resonance caused by the exhaust. I've heard it in an '06 Hemi QCSB 4x2 with a relatively mild FM50 in it. Trust me, if you've got it, you'd trade it in a hearbeat straight up for your ex mother-in-law sitting in the back on every trip, telling you what a failure you are...
