X-Pipe Not Loud Enough. How can I make it louder?
-Thanks
Removing them makes quite a bit more sound that the x-pipe alone.
Not exactly representative of what it will actually sound like cause I could only rev to 4k RPM, but here is my car with an x-pipe and "secondary cats" (inline resonators) removed. Same engine as yours, the M276 3.5L. Be careful of advice from 2012 or previous C300's because they have a different engine, the 3.0L M272.

the car in your profile has half the displacement of my car so your experience will differ.
