the slk55 is the top model-yes, we all know that already. everyone seems to think that performance gains for the other models has to compare to the slk355. what's wrong with trying to make a 200 or 350 perform better than it came from the factory? if no one here has done the kleemann route, i'd suggest looking for a local kleemann dealer/installer in your area to get an idea of how much you're gonna spend for what you want with your car. here is the following list of dealers that i saw on kleemann's website:
