Does anyone have a dyno of a stock C55 after a resonator delete?


Resonator delete with no other exhaustmods gave me a slighter higher
"noice" outside and inside, which I liked since the car from factor is very
muffled down. Compare with a Audi S4 or a RS4 for example, they´re loud!
Resonator delete with Kleemann headers is VERY loud (secondaries in place).
A slight uphill will give you a lot of drone inside the cabin, even the dog
complained!
So I put the resonator back on and now me and the dog are happy again. It´s quiet at
cruise and it roars at full throttle.
My impression is that the resonater original is there to reduce drone.
Maybe the sound is different in a sedan compared to a wagon?
Cold start: Kleemann headers, resonator delete:
