Perforated Tube for the Exhaust on Rotax Max Evo kart engines, specifically the MY 20 Mini Max engine.
This perforated tube allows exhaust gases to flow from the exhaust pipe through the exhaust matting and into the resonator for proper expansion of the exhaust flow and overall performance of the Mini Max engine.
Note: This perforated tube is different in sizing from the Mini Max to the Micro Max. Make sure to use the right tube for your application!
