Hey guys,

So I just purchased my 2014 charger R/T and I've had it for about a month. When I accelerate there everything is normal, when I accelerate at a higher rate I get an odd humming noise. It's pretty loud depending on how much I get into it with the throttle. Just started doing it. Took it back to the dealer and they said they could only replicate it on a cold start and said no you're obviously not test driving the vehicle enough because I've driven it 30-40 miles when the engine is warmed up and the noise is still there. So iam wondering if anyone else has ran through this problem?? Any help much appreciated!!

I don't know where to begin without being able to hear the noise. What area of the car is the noise coming from?

I've posted the video on my YouTube:


You can hear it in the background, it seems that every time I get on it the sound comes and goes. Sometimes won't do it all day! Can't figure it out.

Thanks for your time

I can hear the noise in the background but I can't tell what direction or area of the car the sound is coming from.

I'm thinking it's from around the resonators because in the car you can distinctly hear it from basically under the front seats. Also figured out it doesn't do it in neutral.

I literally just got backed into Friday night and now have go through all that. Hopefully after the body shop I can take it back to the dealer and let them figure it out.

Just don't want to go through hemi withdrawals again haha

Maybe it's your exhaust - the mid mufflers under the seat. It could have a leak or maybe the exhaust clamps need to be tightened.

I don't know much, but aren't the mid mufflers towards the back of the car? Only reason I'm saying is because I've watched them do a mid muffler delete taking out the two in the back.

Actually, the ones in the back are the resonators. The ones in the middle are called mid-mufflers. I would jack up your car on one side and look under there. See if you have any black soot around the exhaust clamps. If you do, you need to tighten them.

sorry to drag up an old post, but did you ever get the issue resolved? My 2011 toxic orange R/T road&track I bought last january to replace my 2011 toxic orange R/T that was totalled this same sound, and I haven't been able to pinpoint it....mine doesn't do it when cold, or when very warm, and it does it under load, and in transients if I'm still or put the car in neutral and rev the engine quickly. any help would be great....

thanks, although I did when I had the car in for a recall last year. I told them about the noise and asked if they could diagnose it. after charging a $50 diagnostic fee, they said they "didn't hear it" and tried to pass it off that because it's a performance model the exhaust is louder....

Hi michiganpat,
We certainly understand your sentiments. We would be happy to escalate a case on your behalf so that a Case Specialist may work alongside your dealer regarding this concern. Please contact us via PM before your next dealer visit. This will allow us enough time to escalate your case and connect you with a Case Specialist before your visit.

I get the same sound. My mechanic pointed out a crack on the exhaust pipe going into the muffler. At different points of temperature, it would do it. Mostly when cold or just starting up in the morning or after sitting for a while. this was because the exhaust was not heated up and the metal expanded to take up the slap in the exhaust pipe. as my mechanic said, it may become more prominent as wear and tear goes on overtime. I did also not a slight exhaust smell when I would be getting in or getting out. I would suggest checking the exhaust pipes, mufflers, resonators and cats for cracks.

mine is a bit of the opposite. I DON'T get it when it's cold, but once the car warms up it is very pronounced. it's loudest with shorter trips, and starts to go away as the car gets hotter (i.e. warm summer day and a lot of freeway driving or aggressive driving)....my guess is there's an internal baffle in the muffler that's broken loose and as things expand w/heat, it stays put when cold, starts rattling/buzzing when warm, but when it's really warm there's enough clearance from expansion it doesn't make as much noise. currently, based on CTScott's youtube thread, I'm looking to replace my mid muffs, but don't want the full bark of straight pipes (although a little louder wouldn't be bad).

I'm currently looking at options w/the least hacking and whacking. I took some measurements of the mid muffs, and it looks like they're approx 17" long case, 4.5" tall 9.75" wide and around 6" center-to-center offset between inlet and outlet. there's a ton of 14" case options in 9x4 up to 10x4.5, and a few 18" case options in 9x4 (namely Magnaflow and Jones exhaust), and one 16" option (summit 304 stainless muffler).

the c-t-c distance is the difficulty, the widest I've found so far is the dynomax 17726 at 5.25" Dynomax Performance 17226 Dynomax Ultra Flo Welded Mufflers | Summit Racing, but it will require a little bit of pipe extension, as it's kinda short to get a good slip fit at 19"

the summit racing one looks like it's close to plug and play w/o any pipe extension Summit Racing SUM-630522-1 Summit Racing® 304 Stainless Steel Mufflers | Summit Racing since cutting the mufflers close to the body will yield about an 18" gap. the c-t-c distance is 5"

I think there might be room for the 18" case options, but I need to crawl under again to check. big thing is the 18" case options are all 9x4, which likely have a c-t-c offset of only 4".

I plan on using band clamps to be able to do it w/o welding.....
