Their exhaust and intake? DC Sports? I personally would not even use their header (JDM or not) but definitely won't use their exhaust and their intake is not a CAI.

Comptech makes one of my favorite intakes and makes a high HP header but for the money SMSP gives better clearance.

My budget setup suggestion is Icebox, OEM JDM 4-1 Header, Fujitsubo Exhaust. (The exhaust is a bit pricey but for that matter the stock exhaust will make decent power and doesn't need to be changed.)
