Welcome! Looks quite smart, I like the coloud coded bits, only the needs the handles white now Gunmetal Speedlines sounds nice, as far as RARB is concerned, I think the Ultra-Racing RARB's which should be on Ebay, are cheaper than the Whiteline one's, but are thinner! I'd recommend getting a K&N Panel Filter is you want to stick with a stock exhaust system, or an Apexi Power Intake if you want an Aftermarket exhaust system! (See my build)
