Why are lawn mower engines so loud, while my car is quiet?

I just came back from a drive and I’m wondering why my 3.0L I6 engine which has roughly 385HP is relatively quiet besides a low growl compared to my extremely loud lawnmower which as a tiny 6HP single cylinder? Would the muffler of my car make that much of a difference?

Your lawnmower has so few power that a muffler would choke it. With a car it lowers the power also a bit, but that’s calculated. That’s also the reason, why tuner cars are so loud: They want their power back.
