Like Stainless Works' standard Silver Thermal Coating, their hyper-aggressive Black-Out thermal coat acts as an insurance policy for your Stainless Works long tube headers and gives them better performance and a much more aggressive look. The Black-Out thermal coating is far more resistant to heat and corrosion than Stainless Works headers alone and will help your high-powered header kit last longer under the most extreme conditions.
Please Note: this is only the Black-Out thermal coating only and not for a complete set of headers.
