    BLOX Racing titanium headers are now available for K-Swap applications. BLOX Racing is extremely proud to be the 1st company to offer production titanium headers. This header is the titanium twin to our current T304 K-Swap unit and still offers the same benefits and gains by maximizing exhaust flow, widening the powerband and increasing horsepower and torque.

    Even though this is based on our current design, that’s where any similarities end. Each is constructed out of 100% Grade 1 titanium, the purest form, which offers exceedingly greater amounts of attributes for, particularly, exhaust components and other high performance and racing products. Each titanium unit is handmade and hand TIG-welded. Considering, the expert skill and craftsmanship that goes into each ensures that each header is constructed the same way, each and every time. This consistency in production allows for proper fitment and seal against exhaust leaks.

    Compared to its T304 twin, the titanium version is 58% lighter!  58% lighter!

    Stainless Steel

    BLOX Racing K-Swap exhaust headers is designed to maximize the engine’s spent exhaust gas and broaden the powerband, increasing horsepower and torque throughout the entire RPM range. This 4-2-1 header is constructed out of 16-gauge, T304 stainless steel and features equal-length, mandrel-bent tubing. The piping and CNC-machined flanges are then TIG-welded for additional strength and reliability.

    With K-series engine swaps becoming more affordable, BLOX Racing’s K-Swap exhaust header is a must-have upgrade. The header is properly designed to provide the necessary ground, oil pan and shift box clearances. There is also no need to modify or cut the chassis’ front cross member prior or during installation. BLOX Racing K-Swap exhaust header is designed to fit Honda EG, EK and DC chassis with K20 or K24 engine swaps using HASport™ or similar style engine mount kits.

    The diameter and lengths of the piping have been extensively optimized and dyno-tested to support over 280WHP naturally-aspirated and over 400WHP supercharged. BLOX Racing also offers K-series camshafts and valvetrain components and throttle bodies, including RBC and K2B throttle body adapters and TPS.
