2012 C63 AMG
I know I know.... But I really need some help..
I know this tread has been made 100x but I have reviewed every single tread and I am not getting the answers I am looking for.




I have a 2012 C63 AMG Coupe and just deleted my secondary cats and resonator and put stainless steel straight pipes and its wayyyyyy too loud for my taste.
I want to quiet it down a bit and loose the high rasp.


What can you guys recommend me to do???? thanks guuys!!!

I have my secondary cats deleted and it is only louder when you are more than 25% throttle. Otherwise you really don't even notice. Maybe you should try putting the stock resonator back on.

Put an X style resonator where the stock resonator was. It will help a lot

Yea, I only heard it when I am climbing up the RPMS more than 25-30% throttle, but I feel the resonator won't be able to restrict much sound..
