have any of u guys replaced ur Catalytic Converter with an aftermarket one, and have also removed ur resonators? because i want to know how it sounds, cause i want an exhaust note that sounds nice, but is not too loud.

E-Klasse

Yes you can replace the cats with aftermarket highflow ones but will not change the sound but give you more flow. Getting rid of the mid muffler will make it louder but not in a bad way if you have a good final muffler like Remus... Do a search on here for exhaust and see what all people have done.
