TSO Garage Note
The ideal armor upgrade for waking up the bottom-end grunt on late-90s KTM big-bores. This heavy 18-gauge chamber thickens up low-end torque to help you pull through technical sections and tight woods, while easily absorbing the brutal trail impacts that would instantly crush a thin stock expansion chamber.
