Jd101b I've never heard that in my 550. It ranges from a low burble to a moderately loud growl, but never "scraping metal".

Darkmann Jasonm did you ever get the "scraping metal" exhaust sound thingy figured out? I'll be taking my 400 out tomorrow for a 4 hr road trip - weather permitting. I'll report after the trip. If you haven't resolved the problem yet, please explain in more details what one needs to do to replicate.

2015 SL400 Exhaust Sound

Hi there! I own a 2015 SL 400 and when I accelerate, there is a “scraping metal” sound coming from the exhaust. Two separate Mercedes dealers have said it’s operating as designed and this is the sound of air pushing through the baffles? Can anyone confirm this is normal?

Thank you!
