The Akrapovič Optional Header (SS), manufacturer and vendor part number E-H7R6, is designed for the Honda CB750 Hornet. Constructed from high-grade stainless steel, this racetrack-oriented header pipe replaces the standard stock header and removes the original catalytic converter to improve exhaust gas flow. Its larger-diameter tubes help reduce restriction, supporting more efficient performance from the twin-cylinder engine while delivering the quality, fit, and finish expected from Akrapovič exhaust components.
When combined with the Akrapovič Slip-On Line (Carbon), the E-H7R6 header produced a tested power increase of 1.6 kW, or 2.2 horsepower, at 9,500 rpm and a torque increase of 3.5 Nm at 6,700 rpm compared with a Honda CB750 Hornet using the standard stock exhaust system. Testing was conducted on the Akrapovič in-house dyno. The system also contributes to a deep, racing-inspired exhaust note that complements the character of the Honda twin-cylinder engine.
The Akrapovič Stainless Steel Header Pipe is designed as an easy plug-and-play installation for compatible Honda CB750 Hornet applications. Remapping is recommended to help optimize fueling and performance after installation, although it is not mandatory. This is a competition-focused exhaust component intended for use exclusively on closed-course racetracks and private competition circuits. Verify motorcycle model and exhaust-system compatibility before installation, and follow all applicable race-use, noise, emissions, and local regulations. Brand: Akrapovič.
