Arrow 52014MI Stainless Steel Racing Header
Short Description Product Description Vehicle Fitment Product Instructions Features Values Headers Material Stainless Steel CO Sensor Plug No Oxygen Sensor Plug Yes DB Killer No Certificate Racing Headers and pipes are a most important component of an exhaust system, making it possible to reach very important gains in terms of power and torque. Made in AISI 304 stainless steel and, for competition Full Titanium systems, in titanium, Arrow headers design comes from the experience gained and the results achieved in years of races at all levels, with the irreplaceable “touch” of the master mechanics working in the R&D: diameters, sections, bends, section changes weldings and layout are carefully designed and developed on the bike to create a product with high performance, durable, reliable and with the unique Arrow style. Depending on engine configuration and its spark timing, the layout can be really different as it’s needed to adapt it to changing needs: that’s why we speak about different schemes like 4:2:1, 4:2:2, 2:1:2, 4:2:1:2 and so on. To follow one scheme or another is a most important decision, to be taken at the very start of the project, and it will influence all the other steps. To avoid unnecessary drag on the flow of exhaust gases, all junctions and connections are made using CNC-machined parts. For the same reason, all welds need to be perfectly made and non-invasive, avoiding any section reduction for the flow of gases.
