not to send you on a wild goose chase, but the guy who had that set up done to his car is SteveL i believe he mostly frequents the benzworld forum... not mbworld... and he has an slk32...

C32 owners do not do this because they got the much better quaife alternative... and us crossfire owners have only recently started purchasing performance products as the warranties are running out and we are finally getting attention via our forum as well...
