You won't want a cat in the header if you're turbo. It will get burned up pretty quick. You'll also want EL especially if going turbo. The difference on N/A is pretty minor with torque response in different areas, but turbo you'll start to see the gap between UEL and EL.

Yes this is what I was looking for, I know my kit comes with an exhaust manifold which is why I don't want to go out and spend 1k on a new header just to have to sell it again when the turbo kit is installed.
