What kind of mods have you done to your CLS?
These recordings are from about a month ago when I recently replaced resonator and mufflers with straight pipe. Both are cold start. Still have the main cat and the secondary cat intact.
Does removing secondary cat, which is just a canister like resonator, increase the exhaust sound? Or anything at all, if anyone knows!!
It's all blacked out, but the front star is painted in gold/bronze and yet to buy black wheels for it and then tune.
I did a few other small things of which I don't have pictures yet. Will upload them later.
BUT do let me know if the secondary cat delete would increase the exhaust note

Do you have video clip of the sound with AMG exhaust on the 550?
And is that exhaust from primary cats to the mufflers?

The wheels are 20x11 in the rear and 20x9 or 9.5 (cant remember).
Thanks for all the kind words
