DESCRIPTION
Power and beauty for your Miata! This Stainless Steel Header by Cobalt is the only header for 99-05 that clears the old Jackson Racing M45 and Moss MP62 "hot side" supercharger kits. The Cobalt header is custom made for the 99-05 Miata using the highest quality materials and workmanship.
* Fits Manual transmission only
Note: 99-00 California cars (we cannot ship this to CA, but there are some CA-spec cars elsewhere in the country) have a cat in the exhaust manifold, so changing to this header will require our Race Header O2 Wiring Kit part # 11-1039 or the check engine light will come on. The O2 Wiring Kit includes a weld in O2 bung which should be placed behind the rear cat. Another option is to use one of our RoadsterSport mid-pipes that have this bung already.

-Header is manufactured from 304 stainless steel
-Primary tubing diameter: 1-5/8"
