Just a side note, that "Cold" rumble during startup is due to the fact that the ECU deliberately keeps the RPMs high for a few seconds after startup to reduce engine wear from cold cylinders.
You can technically modify the ECU to keep the RPMs that high during idle and keep the "rumble".

I took the plunge and have an exhaust shop remove the secondary cats and resonators with straight pipes. Now the car barks and this is the sound that I expect from an AMG, especially a 6.2 liter V8 ![Big Grin](https://mbworld.org/forums/images/smilies/biggrin.gif)
I'm just wondering do I need to send my ECU to Eurocharged after this? If that's the case, it will be another 10 days out of action for my car.
