Akrapovic Header Stainless Steel
Honda CB750 Hornet / 2025
The Optional Header (SS) is targeted at owners looking for increased
performance and weight reduction from motorcycles already equipped with
an Akrapovič Slip-On Line (Carbon) exhaust. The Optional Header (SS) is
constructed from high-grade stainless steel and provides a 53.5% (1.8
kg) weight saving in comparison to the standard stock header. Developed
with larger diameter tubes to allow improved gas flow with less
restriction, the catalytic converter of the stock header is removed to
add to the flow. When fitted with the Slip-On Line (Carbon), power is
increased by 1.6 kW (2.2 hp) at 9,500 rpm, with a torque increase of 3.5
Nm at 6,700 rpm when compared to a Honda CB750 Hornet equipped with the
standard stock exhaust system and tested on the Akrapovič in-house dyno.
Producing a deep, racing sound fully encompassing the twin-cylinder
engine, the Optional Header (SS) is an easy plug-and-play installation,
with remapping recommended, but not mandatory. It is a
racetrack-oriented part and as such is intended for use on closed-course
competition circuits only. Fitting of the optional header will
invalidate the EC/ECE certificate for the Slip-On Line (Carbon). When
installing the Racing Line exhaust system on Euro5+ motorbikes (2 lambda
sensors), the engine check light will appear after identifying a
deviation in the stock catalytic converter´s parameters. THIS
PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR
HIGHWAY USE.
