Finally! A true 100% bolt-on K24 swap S2000 header with a proper 4-2-1 design and correct cylinder pairing.

No more need to modify your old OEM header, or deal with the compromises of the other K swap S2000 headers available. It's compatible with stock exhausts and all common aftermarket options. 

Constructed from 16-gauge 304 stainless steel, the header features 1.75-inch primary runners stepping to 2.25-inch secondaries, a 2.5-inch collector, and an OEM style exhaust flange.  

Dyno proven and built for both street and track use, this header delivers reliable performance without compromising fit or serviceability.

This header has been extensively tested for a full season of Gridlife GLTC with our partners at ASMotorsports on an S2000 race car, ensuring the durability and longevity of every tube, bend, and weld.
