Impala intake + muffler ??
I dont know anything about cars.. but i was thinking about putting a K&N cold air intake, with a flowmaster 40 series muffler on my 2000 impala 3.8L V6.. will the car sound better? and about how much more hp is it going to give anything i could really feel?

You wont really feel any improvement. Maybe about 2 or 3 percent more horsepower, but thats really not much.
Most mufflers have a low sound on a V8 engine , but i never heard it on a V6. Allthough in some shops you can have a "demonstration" of the sound it should give on your car. so just go to a specialised shop for a demo.
The K&N filters are very good on most cars. The problem with some cars is, that they need some room to find their "cold air". (I know about some Audi's where the K&N just melts away because its too close to the radiators or engine).
The advantage on those K&N filters is their low maintenance and easy to clean. they are expensive though (about 20 times more expensive then your average paper filter.). But still, i would advice the K&N to everyone. (Even the oil filters).
Fixing those new items on your car , will influence your horsepower. I'm not using the word "boost" because well... it may turn out the other way. I know people who just put on the filter, weld the exhaust and take in on the freeway, surprised that it doesnt make any difference at all.
It takes some fine tuning to get the maximum result out of your exhaust and new air filter. And only someone with the right material can do that for you.
See it as a runner who breaths through his mouth. He makes an "O" with his mouth while running. All of the sudden he decides to make his "O" bigger. At first you would think that would be a good idea, because he gets more oxygen. But after a few meters, the runner will feel that he takes too much oxygen, that his lungs cant keep up the pace and his blood is unable to pump the oxygen fast enough through his body.
What I'm trying to say is... you MIGHT find an increase of 10 percent horsepower in your car IF you let someone CALIBRATE your car to the utmost PERFECTION. If you decide not to do that...then you might possibly find that your car all of the sudden runs like a citroën berlingo 1900 diesel without turbo. So basically. The amount of horsepower you get from your car, will largely depend on the skills of your mechanic.
And as a wise man once said. "you easily get used to speed."
And as another wise man once said " its not horsepower that counts. Its torque!"

if you do decide to get a k&n intake do you have one in mind? there are a few places that make them for the 3.8
if you want you can get a k&n filter and make your own intake that goes into the fender well like this. this is on my 3.4 but you can do the same thing with the 3.8.............
replacing the muffler will make it sound a little different. but if you're going to replace the muffler you might as well get a whole new catback exhaust. if you want it louder remove the resonator. i dont have a resonator on mine and its fairly loud, but thats the way i wanted it. i suggest getting a downpipe upgrade also if you're going to do the exhaust. this will eliminate the restrictive u-bend thats in the exhaust, plus the DP will come with a highflow cat. with these upgrades you will feel a difference. i dont know what koffietje is talking about having someone "calibrate" your puter because the 3.8 responds nicely to these mods without having anything done to the pcm.
after you get these things done just unhook the negative post on the battery for 30 mins and the pcm will relearn the fuel trims automatically. it will take a few drive cycles to smooth everthing out but you dont have to calibrate anything.
