Does it happen at startup or when engine is cold - or when fully warmed up?
Outside temp when this is most noticable, octane of gas used (same or different brand).
Just need a bit more info on the noise.

at cold it is definitely loud at idle, but when warm it's quiet at idle, however, when i step on the gas then you can totally hear the engine working,
outside temp in CA is like 40-50F recently, i've been trying to use 89 octane gas,

Although the Corolla is well insulated for a small car, it is by no means a Lexus, far from it.
The engine in my 05 is quite noisy beyond 3000 rpm. Doesn't have that Honda purr.
And it is VERY noisy upon start up when VERY cold outside. But in CA, that is definitely not your problem.

From what you described - louder when cold but quiet when warms - sounds normal to me. As far a the engine really "working hard" at speed - it should be louder to a certain point. If it is pinging badly - higher octane of gas will help. If the engine is thrashy (lots of valvetrain noise) could be a problem with the VVT-i system.

It is a part of the character of this car, the 1ZZ-FE engine is noisy, period. The car reviewers often described that as an "agrarian" sound, not pleasant at all. Not every 4-banges is like that, the one I have in Subaru (2.5L boxer) has a very pleasant tone, even when redlined, but the exhaust of boxer is different from that of inline engine.
i've had many 4 cylinders, it just seems that the corolla is well built and shouldn't be as noisy...hmmm, maybe i am expecting too much huh?
But I like MPG in Toyota much better, just can't have it all.

But the corolla isn't all that well insulated so unless you're driving madly, road noise is probably going to be a bigger issue than engine noise (it is for me anyway).

You shouldn't have to use 89 octane, though. I hate to see you spend the extra money--this is supposed to be an economy car!
If you want to compare with other '03 LE's, you might go test-drive a couple of used ones, either at a dealer or a rental car sales agency. I bought mine at Hertz Car Sales, and they often have several Corolla LE's. All of the cars Hertz sells have between 25K and 30K miles, so it would be equivalent to your mileage. Go to www.HertzCarSales.com and you can put in your location to see if there's a branch near you. You can search their inventory to see if they have any '03 LE's.

My 03 is noisy warming up but purrs when warm on 87 octane.
If yours is noisier than the used car, perhaps a run up on the lift to check exhaust system for leaks.

To me the noise is normal, possibly a limitation of Toyota technology.

Engine sure had that "agrarian" sound again. But a fairly nice little tractor soundtrack, if you don't push it and let the revs low. Which I always do when this cold.
