As you listen to this monster on the Dynapack dyno, just ask yourself this: “Why shouldn’t my C63 sound like this?”

Never liked the sound of the Akrapovic Titanium Exhaust for the C63, sounds way to tinny and raspy. Agency Power or IPE are much better IMO.

Wasn't that thunderous to be honest. If you like it, doesn't matter what anyone else thinks.

I honestly haven't heard a single aftermarket exhaust that sounds better than stock.

Akrapovic exhaust note is pretty tame.

Do valve tronic exhaust really make a huge difference in sound? (Capristo, FI)
I have been looking for sounds clips of the (FI) Frequency Intelligent exhaust on stock headers or any M156... No luck.

Agreed. Of course, I barely see any other C63's in my area so I haven't heard any in person, but so far, none of the exhausts sound clips have enticed me.
