Agency Power Valved Catback HP gain
is it true that the AP Catback will give me a little bit more peak power ?

Agency Power homepage :
"With the powerful AMG V8 engine, the Agency Power exhaust extracts an additional 24 rwhp and 16 ft lbs of torque. These gains game from a before and after muffler on our C63 with headers and mid section already installed."
Somebody had dynoed before and after ?

Thanks...
Cheers!
Alex
