Why do you want a loud raspy sounding car anyway?
Keep the original parts so if you sell the car or come to your senses, you can put the original items back on the car.
I'd double check the warranty. I can see removing the cats may void warranty but a cat back bolt on exhaust system should not.
Is the warranty from Mercedes or one of those 3rd party providers? They sell you that **** to make money, not to try and actually cover you so keep that in mind.

Anything modification done to the exhaust BEFORE the primary cats should not void the warranty. In order for them to void any warranty they need to prove that what you did broke whatever broke.
In other words, do not mess with the cats and you'll be fine (Not sure about secondary cats though)
