2019 C63S Particle Filters for US?




The quieter nature of the 2019 exhaust has two main reasons. The noise emissions in Europe are measured below 4000 rpm, and they now have to be measured with the valves open in case of valved exhaust. This latter part is a big change. Previously, the noise regulations had to only be met with the valves closed, so manufacturers had an out to make the cars louder than the regulations allowed when the valves were open. The reduced nature of the pops&bangs has nothing to do with the filter. The pops&bang are created by changing the ignition timing and letting the combustion extend into the exhaust cycle, so the air/fuel mixture continues to burn in the exhaust. This is all software and if it wasn't for the noise regulations, AMG could make this cars pop&bang how much they want below 4000 rpm, particulate filter or not. One possible reason that they don't do it could also be that the pops&bangs are not good for the filter when the car is equipped with it, but AMG might not wanna change the ECU software to deliver more pops&bangs in markets w/o the filter to reduce the potential different configurations they have to support.

* Irrelevant question -- what does c63cs mean ? c63s coupe?




Yes, C63CS = Coupe, C63WS = Sedan and C63SS = Wagon. It's the official abbreviation MB uses. It's how the car shows up in Mercedes Me etc.

I do use the car as a GT, which is what it is meant to be. No, I can't drive at the speeds one can drive in Germany, but I do a lot of long distance road trips and the 2019 C63 is a phenomenal long distance cruiser. I'm also lucky to have access to deserted canyon roads where I can open it up and enjoy all the noise and handling prowess w/o much fear of law enforcement. I honestly probably wouldn't own this car if I didn't have the opportunities to fully enjoy it. I was born in Switzerland originally, so my passion is ripping up and down curvy mountain roads, the likes one can find all over the Alps and thankfully here in California.
Just as an example of a road I got to drive while in Europe. This is the Stelvio pass, which is the highest paved mountain pass road in the Eastern Alps. 48 hairpins to 9000 feet elevation. This is what this car is made for.

Mountain View Road - a winding 20-mile stretch between Hwy 1 and Hwy 128. The road was good the first 10 miles, and really terrible in the last ten. It was full of potholes and very narrow with blind curves (without lane markings). Reminded me of Kahekili Highway in Maui but instead of the dangerous cliffs, just shallow ditches on the sides of the road instead
