Performance upgrade
 

Hello everyone,

Ibought a 2001 E200 kompressor a month ago. Im thinking of replacing the catalytic converter with a higher flowresonator and putting in a k&n air filter. (Im living in the middle east where we dont have emission control).
Will replacing the cat. and air filter make noticable difference?

How can I clear a (defective light) warning , and i checked them all (head, tail, door lights, etc).

Also any good site for mercedes parts? all the ones I opened they dont have parts for 2001 e200k.

Thanks.
