i wanted to know if i should start racing my bmw 328i (stock) the way it is to get money and as i go on buy things for it or should i get things first and race it. also what should i buy first?

Do whatever you want man. Race it, garage it, whatever. It's your car...have fun and do what you want with it. Intake, exhaust and header are never a bad place to start. They help your engine breathe better, are easily to install, and will help with further modifications.

This thread should probably be moved to the non-specific forum.

From a fellow BMW non M owner...don't race for any money unless its against like a stock Civic or something. Or a totall ricer that you know will fuck up and loose somehow. Get used to people giving you shit for not owning an M3 but racing. And aftermarket parts will cost an arm and most of your leg. However, if you enjoy it (as I do), go for it and have fun, and welcome to the boards.
