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?

Cost. Your lawnmower is a piece of junk.
Also the more cylinders you add, the less THUMP the exhaust has to deal with. It becomes more of a steady air stream. This is easier to tune.
But mostly the mower is built to a price not a quality. Also, once you get a modern electric machine there is no going back. Quiet is worth paying for, and a battery every 7-15 years is cheaper than fuel now. If it has a LFP lithium battery it could go 20 years. Yes, batteries have come a long way.
