throttle body $200-$250 new $100-$150 used
Header anywhere from $100 to $350 ish depending on what kind and new vs used. The SVT header setup is pretty much the only way to go with these cars. you can read more HERE
Flex pipe $150ish new
Catback $100-$600 again depending on new or used and type. (I LOVE my MBRP btw)
and a tune runs $400 plus shipping from Tom 1tubrofocus on here, which includes lifetime free updates as you add NA mods
so as you can see cost will vary quite a bit depending on how you do it.
