    Hello Nick, welcome aboard!

    Headers... folks will chime with their preferences, and yes, you'll need to tune after (with stock exhaust, cats light off in xx minutes. with headers the cats are further away from the engine, and take longer to 'light off'. The tune will, among other things, tell the computer "it will take xxx minutes for the cats to light off")

    Now, more than ever, avoid the "cheap Chinese stuff" and buy GOOD American made headers (Kooks, ARH, etc). My ARH's have been trouble-free for 8 years or so.
