Hello, I have purchased a new 2019 C63S saloon and the car is too quite for my liking. I previously has an M3 and changed the exhaust from bmw and this sounded great with no warranty issues. Does anyone have a 2019 model and have they changed their exhausts system? If so which one would you recommend? And has anyone had any warranty issues with changing the exhaust system? Any help would be greatly appreciated.
