Best intake, headers, and exhaust for automatic 2000 tiburon

[srfantom]

i'm in the process of fixing up my 2000 tiburon, i am ordering cross drilled slotted brakes, brake line, the cuda body kit and am now moving on for a performance upgrade on the engine. I am wondering if anyone has any opinions on what would give the best performance after replacing the intake, headers and exhaust. What company should I go with and what are the best models that I should be looking at. Help would be greatly appreciated.
