Actually, if he goes SC he will want to stick with a 2.5" exhaust, a 3" is worthless unless you are moving to a turbo environment.
For turbo you can use your exhaust you have, but if you want to move above 480whp you will need to move to a 3" exhaust. Headers are good with a SC, both short or long tube and are a solid investment but not if you are going for a turbo setup. On the front side I would stick with stock for now as with most kits you get everything you need. Intake, piping, etc.
