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 NC cars!

For universal applications using our 86 transmission solution, you will need to shave down the 86 adapter and 86 transmission about 1/4 inch for the header to install correctly.
