Our NC K Swap 4-2-1 header provides the perfect blend of fitment, durability, and performance for the NC chassis, as well as other RWD K series applications.

It features 304 stainless construction, 1.75" primary runners, 2.25" secondary runners, a 2.5" collector, and 3" V-band outlet. This header is also built with our preferred cylinder pairing of runners 1-4 and 2-3.

It fits in the factory NC header location, and is even compatible with the stock header heat shield.

This header has been confirmed to fit on both LHD and RHD cars!
