What I've just recently noticed is a little hard to explain.
I have the 4.6L engine, and have always felt the power is more than adequate - in fact, it's pretty quick.
Around 9,800 miles I noticed a subtle change. The exhaust sound is a little louder and deeper. It also seems to have just a bit more power. It's almost as if I have added a new exhaust or intake, but I haven't. By the way, no complaints, I'm just a bit perplexed.
Has anybody else, 4.6 L or 5.4 L, noticed a similar change after driving 8 - 10,000 miles ???

Yes! The engine is getting broke in! It takes a long time for these engines to break in, but once they do, you will feel more power and which will make you exhaust sound deeper. I noticed the same thing with my 4.6L after after 8K miles! There much nicer after there getting broke in!
