I need help with modifying a Saab 9-3?

[The Larges]

I have decided on a 2004 Saab 9-3 as my first car, since my mother will give me a good price on hers. It is a semiautomatic, which is fine for now, and it has the 2.0T. Its nice, luxurious, and pretty damn fast, but I need to modify it to my likings. I know how to do certain things, but there is one thing I do not know how to do, nor do I know if it is possible or not. How (if it is possible) would I make the cabin loud as hell? I want the exhaust noise very present, since I appreciate things that people who buy them new hate.

Install an aftermarket exhaust system complete with a header, downpipe, and cat-back exhaust. I would go with Magnaflow on the cat-back. The header and downpipe, you would have to do your own research. Adding a blow off valve to the turbo would help you out too if you want to make the car louder.
