Yoshimura has new GP Magnum slip-ons for 2024-25 Triumph Scrambler/Speed 400 models.
Available in a choice of satin stainless steel or titanium with blued effects (pictured), the slip-on is three pounds lighter than the stock unit and adds a claimed 2.08 percent more horsepower (at 8000 rpm) and a 3.8 percent increase in torque (at 6300 rpm). The GP Magnum comes with a sound insert, but it is removable for a more aggressive tone.
