Blox Racing - K-Series 4-2-1 Swap Exhaust Header

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

With K-series engine swaps becoming more affordable and popular, the BLOX Racing 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.

The diameter and lengths of the piping have been extensively optimized and dyno-tested to support over 280WHP naturally-aspirated and over 400WHP supercharged.

The BLOX Racing K-Swap exhaust header is designed to fit EG / EK / DC chassis’ with K20 or K24 engine swaps using HASport™ or similar style engine mount kits.
