2019 C43 coupe
Air/Hissing noise
I just purchased a 2019 C43 coupe with the AMG performance exhaust last week. When I accelerate, the vehicle makes a loud hissing noise. Kinda like air is being blown out of the side. It’s very loud, and doesn’t sound normal. Also, I feel like the car is not accelerating as quick as it should. Honestly seems a little slow... Any idea what this may be?

Thats understandable but why is there loss of power? And why it’s hissing louder than usual to the point that it starts to whistle? Why should the car stay going 35mph on the highway even though I’m flooring the crap out of the accelerator? That’s not normal behavior to me or anyone having the same problem with the vehicle. When I first got the car I didn’t experience any of that, so it doesn’t matter if it’s turbocharge or not, our cars come with 385-89 hp I shouldn’t have to struggle to over take a slow vehicle on the next lane.
