Ultrex or Kinugawa Headers sold by Kando Dynamics on Ebay are good. Same product, both of which are unbranded Tomei expreme units. Very good quality, they fit and come with all associated hardware - much better than the cheaper units I've come across.

Had mine ceramic coated by CIC, heat wrap is cheaper though but would recommend researching both processes before making a decision.

Chose UEL, gave the car a much more aggressive sound which I was more than happy with. Have had mine on since February without issue.
