W209 exhausts mods

Wondering if anyone has fitted primary sports cats, and removed secondary cats with the clk55 back box. Any noticeable gains and improve sound.

Hi, I have the second cat removed and box removed on my w208 clk55, sounds awesome, like a c63,
best sound ever! Do it !!!

So how would a '63 sound if I did the same???

Does the 209 clk55 have resonator box??? I'm sure I didn't see any only the 208 clk55 has them I think.
I will be leaving the primary cats and remove the 2 middle ones. Would the noise increase with the OEM back box

Couldn't say on the w209. But I have the standard back box and it's certainly very different to oem sound
