Power and beauty for your Miata! Our Performance Stainless Steel Header by Cobalt is the finest, more durable Stainless Steel Header available. The Cobalt header is custom made for the 99-05 Miata using the highest quality materials and workmanship.

Note: 99-00 California cars will require 903-700 or the check engine light will come on. The 903-700 kit includes a weld in O2 bung which should be placed behind the rear cat. Another option is to use one of the Cobalt mid-pipes 909-960 & 909-962 that have this bung already. This will not make it CARB compliant, it simply keeps the light off.

  • -Secondary tubing diameter: 1-7/8"
