Do W222 S550s come with valved exhaust?


this is what I found out reviewing some car auctions... OE or not? The car is S500/550, 2013 (Edition 1).

Looks cobbled together to me. The welds on the valve look sloppy.

Based on this, I was under the impression that in some configurations, in some markets, there was an exhaust valve feature in S550s: https://www.renntechmercedes.com/ind...222-550-detail

Yes, the second pipe is normally closed and opens in Sport mode under more aggressive acceleration. You can here the difference.

Oh ya thats stock. My 2017 had that same setup. Like was said it only opens in Sport mode pretty sure. I think it might only be on the amg line although not really sure. I did also have a 2015 non amg line and that car did not have that valve. I'm pretty sure my 2018 S560 has electronic valves on the mufflers and that those of the vacuum variety as pictured.

interesting... from the inventory I see the following "AMG" options:


Code:
772 AMG STYLING PACKAGE-FRONT SPOILER, SIDE SKIRT
793 AMG 19" DOUBLE-SPOKE WHEELS WITH MIXED TIRES
950 AMG SPORTS PACKAGE

So my money goes on option 950 then

Thanks! Next step will be to hear it and see if this valve can be adjusted somehow...

I wired mine open for a while, the car was a little bit louder, not a real lot though.

The exhaust is the same on a sport package car and a regular one.

Yes, the pre-face lift W222 has vacuum actuated exhaust valving, while it's electronic in the face lift models. The valving is adjusted according to speed and engine mode.
