Making your own header's, exhaust, etc.

I was wondering if anyone can give me any tips, help, info or anything that tell's me how I can make my own exhaust. I don't have a car or nothing yet but I am going to be getting one hopefully this summer if thing's go right so I wan't to learn how to do this and practice a bit. I wan't something that will sound really good, I don't care for the lower kind of sound like flow masters, I wan't something with more of a rumble and... well don't know how to put this but something with more or a "HOD ROD" sound. I think you guy's might get what I mean but I know that there's ton's of different sounds but I like a louder more rumbling sound and something that sound's like it has radical cam's in it. I am sure that "Streets" has some link's or something. haha Thanks in advance. Oh yeah pictures of stuff on making it and all would be great as well, just anything to help. Thanks a lot!

Thanks a lot streets, I will check that out tomarrow when I got time.
