I got a Renntech tune on my 19' C43 and there is no noticeable exhaust change. You could specifically ask for a burble tune I'm pretty sure but I think the burbles sound pretty bad and tinny.

I chose Renntech since, in my opinion, they are the most reliable, conservative, and wise tunning companies out there. I wish I had Dynoed the car before and after, so I have no numbers to give... I could try the AMG hp readout on the screen but I don't know if that would be very accurate.
