Description
Akrapovic Racing Line (Titanium) S-Y7R12-APT for Yamaha R7 2021–2025
Power: 4.3 kW at 9,700 rpm
Torque: 2.9 Nm at 5,500 rpm
Weight: 3.0 kg
This complete exhaust system is constructed with a high-grade, lightweight titanium outer sleeve and end cap for the muffler, along with a stainless-steel connecting pipe and headers. It weighs 3.0 kg less than the standard stock exhaust. A noise insert is included in the package because the open version of the system has no catalytic converter and was designed for use on racetracks or closed courses only. Designed to blend seamlessly with the bike’s lines, the resonator is located under the body, concealed by the lower fairings, and the muffler exits on the right side of the bike. It features an eye-catching heat shield, inspired by those on the Yamaha R6 and R1. Impressive performance gains of 4.3 kW (5.9 hp) at 9,700 rpm and an additional 2.9 Nm at 5,500 rpm were achieved during testing on the Akrapovič dyno compared to a standard stock exhaust. The racing sound lives up to the bike’s sporty reputation.
A black-coated aluminum muffler bracket for the R7 without the passenger footpegs is available as an option.
