Waiting for my car in May so i'm planning my mod path from now, so over next winter might get a few goodies for it.

After test driving a few different cars, i realize the car is pretty quiet under normal driving. Would removing the resonators improve this slightly? I don't want too loud.

Thanks guys

Removing the resonators and adding straight pipes will definitely make the car sound much more aggressive.

Here is a exhaust diagram for the C63.

thank you, are the resonators #4 or the ones right above the #11 in the diagram?
and looks like an h pipe setup stock correct?

The resonators are above #11 but are actually part of #8. I have read that the resonators have a small H-Pipe between them. If you take them out you will need to make one cut between the resonator and the muffler on the passenger side. There is also an X-Pipe available that replaces the secondary cats (#4) and requires one cut before the secondary cats on the driver's side. There is information on these mods with sound clips in this forum.

thank you, I'll search the forums, but if you have any threads that stick out in your mind. Could you link it here?

Here is a recent thread: https://mbworld.org/forums/c63-amg-w...or-delete.html

Also search on _AMG_ and he has some video of his install and pics as well.

Does the exhaust system have vacuum operated Bipass valves similar to Porsche and Ferrari.
