C63s valves
Hi, on my C63S, I had the performance exhaust, but the previous owner replaced it with a full cat-back exhaust system that uses oem valve motors. Now, when I turn on the car for about 5 seconds I hear a ticking noise coming from the back by the valves. The valve button works until stops after the ticking stops. It doesn’t do anything after that. Why could this be?
I also checked underneath the car everything seems to be plugged in.

I only know aftermarket exhausts which they use the oem valve e-motors. it makes sense.
Ask them.

The answer was for when you asked about the brand and I didn't explain quite right about the valves which you were correct they are the oem e motors and upon checking they are connected and as for the website Yes I know Redstar discontinued their exhaust system 3 years ago now they only make downpipes for c63s now thanks for your help
