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..

Any brand in specific?

Put the stock res back on and it brings down the volume some and still has the low grumble lots of videos on the sound out there with just cat delete

longbow0404

no brand just the style of the resonator. I did that after removing both cats (front and back)

So, basically its still straight pipes but welded into an x pipe??

longbow0404

yeap!!! but it needs to be resonated, not just and X pipe.

jmueller

It will.
