W205 c200-C250-C300 remove second cat
Does anyone removed his secondary cat from his w205 c200\c250\c300 ?
I already removed one resonator, and tryed to removed the mufflers, but it gives to much drone on cruise speed.
So i placed the mufflers back and installed a exhaust valve so i can turn it off on cruisespeed.
sound is ok now, but in my opinion it could be a bit more.
is there anything which i can do, like a second cat remove ?
see the picture below this is how my exhaust line is now.
