Don't know - but I think this probably belongs in the bodywork section !! (moved!)
I would also be interested in some of these. The "straight" type will be no good, as the tips of the exhaust pipes point down on our cars, so it needs to be something that curves back up and exits straight out.
I know that for the W211, RichardM has fitted some which bolt onto the downpipes, and exit straight back - but don't actually route the exhaust gas through ! Wonder if there's something similar for the W202, and what it would look like ?
