New 19 Daytona has what I believe is an exhaust rattle at about 2k RPM. When I took to the dealership they said I needed a new exhaust. They swapped exhaust told it was fixed and rattle was still there. Any ideas or anyone else have this issue. There is no rattle when I rev the car to 2k in park or when I accelerate quickly. Thanks in advance.

A side note it doesn't do this while in sport mode. Maybe the active exhaust valve?

I had similar experience with my 2013, and it resolved when resonator part that was rattling broke completely and did less resonating control.

I also took mine to dealer and they couldn’t hear it. Seemed to kick in at a specific frequency and RPM around 2-2500 RPM.

Another related story.... Once I was on Airplane flying to China, and heard rattle. When I opened window to show attendant a piece of the wing fell off... I got to meet pilot and got free drinks. LOL

Moral of story... if you let it rattle long enough, it will fail and then you’ll know what broke and if you’re lucky, get free drinks.

I have this same problem, I took my active exhaust valves apart n put some lithium grease on. After putting it back together I get a rattle from 1500-2000 rpm. Sport mode is fine. If you find anything I’d love to hear about it.

I have a Scat pack that does the same exact thing. I've had a mid muffler delete for a year and the sound just started about 3 months ago.(2 dealership and 2 muffler shop no help) Thinking of cut resonator next I believe it's coming from them. Any ideals?

Also 1 dealership did change my active exhaust because they said that was the problem and when I picked it up it wasn't as bad but still had a rattle at 2000 rpms

So I went ahead and hooked up some exhaust valve simulators from active exhaust solutions. Came out to $165 but worth it.

So they'll replace the active exhaust?

No you reinstall the oem valves but a spacer is put in to move the mechanical portion of the valve, so you don’t throw codes. A pin will hold the valve on the exhaust wide open. It’s a weird install where you clamp it to your emergency brake cable but it doesn’t impede operation of the brake.

Curious to see how the big 392 sounds with mid delete and exhaust sim. My 5.7 is nice With the same mods but I’ve got the itch to move up to the hellcat very shortly...pending the dreaded wife approval. Hahaha

Also that hellcat will be awesome but from experience the scat pack is more fun to drive then the hellcat. 1. The throttle response is faster then the hellcat ( the of course is faster) but it takes more time to get the gas to the pedal the the scat.
2. On the street with the right tire setup the scat will give the hellcat hell on a 0 to 100.
It's a better street car plus 10,000 cheaper.
I love the big brother Hellcat now but those are fact!

Hey guys,

I am from germany with a 2019 Charger R/T Daytona and I also have the famous AE rattle, but I think I have found somewhat of a solution without any simulators.

My issue:
Bought a fresh imported Charger and noticed the rattle after a few days of owning the vehicle. The car was too quiet anyway so I just bought some MFER-1 simulators - it fixed by issue for now but...
I deleted my mid mufflers aswell and in germany the noise laws are very strict. To "mask" the brutal sound of the muffler delete and be able to fool the Police, I wanted a working Active Exhaust, so I deleted my MFER-1 installation - aaand the annoyingf rattle was back.
Since the re-installation of the MFER-1 is not ideal because of the noise level in germany - I went to search for a soution.

The rattle reason:
I have identified the exact thing that rattles: it is the head of the valve where the spring of the motor sits in. If I detach the Motor and Spring of the valve, and put it into closing position, I can manually "rattle" the head up and down. This is what causes the annoying rattle at 2-3k rpm - just alot quicker as you would do it manualy.

The "fix":
So here is my temporary fix that needs some more work (just discovered it today).

1. I took a regular O-Ring to seal of oil or coolingwater made out of rubber.
2. Attach the O-Ring below the Valve Head, in between the red lines is the O Ring (see Screenshot)
3. Now the valve head has waaay less of a gap to rattle
It fixed my rattle to about 90%, the 10% is still a very quiet rattle at 2k rpm but it is barely noticeable.

(please ignore the golden exhaust paste - I really tried 100 things to stop the rattle)


Here is the part that needs work:

• my O-Rings are not heat resistant, they might melt so close to the exhaust
• the O-Rings sit at the "stoppers" of full open or full closed positions. They might wear out after some days/weeks of driving with normal working valves and snap
• one O-Ring has missplaced itself because of the movement of the valve, so I had to place it correctly again
• I tried 2 O-rings but they slipped off each other
• maybe someone knows a better material or part instead of an O-Ring that still tightens the gap but is more durable?

If you have any ideas how to improve this fix so we can move it from temporary to forever, I would appreciate it.
