Proflow's T-304 stainless steel headers are manufactured from a higher percentage of chromium and nickel elements making the metal harder, stronger, and more corrosion resistant than less expensive 409. Only a handful of manufacturers build their headers in stainless; and they typically use Type 409 grade material. These headers will retain a cleaner look and hold up to extreme temperatures.
