TSO Garage Note
The ultimate armor upgrade for taming and harnessing the massive torque of the mid-90s KTM 360. This heavy 18-gauge chamber builds a broad, tractable bottom-end and lower midrange so you can short-shift and lug through nasty terrain with total control, while easily shrugging off the heavy impacts that would crush a stock pipe.
