This study descriptively compares maximum power, maximum torque, and the engine speeds at which these peaks occur on a two-stroke Kawasaki Ninja RR equipped with a standard exhaust, Brand A racing exhaust, and Brand B racing exhaust. The data comprise one dynamometer result sheet for each configuration. The standard exhaust recorded 39.30 HP at 10,305 rpm and 28.77 Nm at 9,071 rpm; Brand A recorded 46.80 HP at 11,409 rpm and 29.54 Nm at 11,080 rpm; and Brand B recorded 47.80 HP at 11,459 rpm and 30.79 Nm at 9,454 rpm. Relative to the standard exhaust peak values, the differences in peak power for Brands A and B were +19.08% and +21.63%, respectively, while the differences in peak torque were +2.68% and +7.02%. These comparisons involve peaks reached at different engine speeds rather than measurements at identical rpm. Because repeated tests, raw data, correction-standard information, and complete documentation of testing conditions are unavailable, the results cannot establish statistical significance or overall performance superiority. The graphs presented are illustrative reconstructions, not raw instrument data.
