They are manufactured from high-quality 1-5/8-inch diameter 304 stainless steel tubes, offering maximum corrosion resistance and superior durability. Additionally, these stainless steel tubes are CNC mandrel bent creating a turbulence-free inner surface before getting expertly welded for added rigidity. Meanwhile, their 3/8-inch thick stainless steel flanges are similarly machined before getting welded to ensure a leak-free seal when installed. Finally, these header assemblies are treated with a specialty natural coating that provides outstanding corrosion and thermal protection.
These shorty headers are CARB certified under CARB EO number: D-57-33, making them completely street legal in all 50 states.
