New here needs some advice

Hi everyone I’m new here haven’t had a lot Of time to browse around yet so I’m sure there are threads on this already. Anyhow just picked up a 2006 TRX450R and I want to start upgrading. Looking at what I consider the basics first, intake rejet, and exhaust. My questions are.. What is a winning combination? As well as bang for buck? All opinions are appreciated. Thanks in advance.
