Long tube headers are typically used for higher RPM horsepower but can also increase mid-range torque in applications where there is room to fit a long tube design. 1 5/8" Primary Tubing Diameter, 3" Collector Port Diameter, Same as Port Port Shape. Metallic Ceramic Coating protects and extends the life of headers by creating a thermal barrier, significantly lowering under-hood temperatures and protecting the substrate metal from thermal fatigue. The coating is polished with a vibratory finishing process for a high luster aluminum appearance, making the surface harder and 60% more corrosion resistant.
