I have a like new Racing Beat header for the 1.6 (90-93 NA) Miata. I was racing a Spec Miata, had to get out of real racing due to health issues, so I was just doing track days with the Spec Miata, with no rules to stick to I added the header. Later I sold the SM and put the stock header back in to make it SM legal. The Racing Beat header has three track days on it , or less than 500 miles. These are $448.00 on the Racing Beat web site. I am asking $325 plus shipping. Can be picked up n Vero Beach FL. Thanks Jerry
