Trouble finding parts.

So I have a 2001 acura3.2cl its not a type s wish it was. But it is my car its fully payed off so ive decided i want to start putting some money into it. But the only trouble is im having problems locating parts for it. Majority of places dont have any of the things im trying to locate. Granite I'm a huge car lover but im not extremely fluent in how everything works. Im still learnin. Any help would be greatly appreciated. I really want to drop it, get new exhaust(which is hard to find), get cold air intake system put in etc. I love this car being my first and want to have somethin i can be proud of. the car in my avatar isnt mine. I'll have pics of mine up tomoro or monday probably. Its definetly nothing special right now but i want it to be.  

Since you said its the Acura 3.2CL I'm guessing the engine is a J32.  The first article I'm linking is about a Honda Civic build but the guy who owns the car is using a J32 engine, so you could take some hints from him.  The 2nd article is about a 2003 CL, which I'm hoping should help since I doubt there are many differences between the 2001 and 2003 CLs.

Just go off the parts list mentioned in the articles.  A simple google search should produce vendors who sell them.
