e420

I own a 1997 Mercedes-Benz e420. I'm looking to give it some more power and aggression with a new exhaust system/muffler, but i dont know of any good brands for Mercedes. I want a clean sounding, aggressive sound, that won't take away from the classy feel and look of a Benz. Any suggestions?

i have a mercedes E420 and the radio is asking for a code???......do any one now what the code is??

in search of good web site for ordering parts for 1997 mb E420 without going through Mercedes
