Off-Road MX Competition full system with carby end cap The ending point of the development work done by Arrow in the past years is the Off-Road MX Competition product range. The experience made in years spent fulfilling top Off-Road teams needs and requirements led to a series of victories and satisfaction (a 8-years-long strip of World Titles in MX1, since 1999) but this led also to Off-Road MX Competition systems. Exhausts made using the same technology we had to develop on the off-road tracks: a break-through design, components made using CNC-controlled machines, advanced materials, production, welding and assembly processes highly demanding and at the top. Off-Road MX Competition exhausts are made by 3 major parts: header, mid-pipe and silencer. Junctions between these parts are made by CNC-made components to ensure no gas leaks, a perfect coupling thanks to severe control of tolerances, reliability and a long-lasting performance.
