SL55/63/65/R230 AMG: Growling sound

Growling sound
Good morning. I recently purchased a 2014 SL63 AMG. The car looks and runs great. There is a very noticeable growling sound on start-up and idle at times. I had it serviced at a European shop and they said it is normal. It is very noticeable and sounds like it could be related to exhaust. Any ideas would be helpful. Thanks
