Looking at C230 Kompressor coupe and noticed that whne started cold they all sound as if they have an exhaust leak. Goes away when warmed to normal operating temp. This has been true for all I've seen, including SLK's. Some are loudert han others but they all do this. Anyone know what it is?
Thanks

I don't think so, this sounds like an exhaust leak and every 230 Kompressor I've seen does it. They can be new, pre-owned, coupe, sedan or SLK.
I'm surprised no one can answer this, the dealer's typical reply is they all do that.
I would appreciate some help here.
