DC Sports 3-1 Ceramic Header for the Nissan 350z/G35 chassis is constructed from quality T-409, mandrel bent stainless steel piping, and CNC machined flanges. Every header is tig welded by hand, both outside and inside of any joints. Larger than stock diameter piping, mandrel bends, and equal-length primary runners ensure a smooth and unstructured path for exhaust gases. This leads to improved HP and TQ throughout your entire power band.  Ceramic coated to reduce under hood temps and combats corrosive road conditions, our coating will continue to provide protection at temperatures up to 1200 degrees Fahrenheit. This header is 50 State C.A.R.B Certified, making it legal for use in any state across the USA.
