AKRAPOVIC Evolution Line Exhaust System - Titanium - YZ450F S-Y4MET17-FDHLTA

Evolution Line Exhaust System - Titanium - YZ450F
Constructed completely from lightweight, high-grade titanium alloys, this system offers a weight saving of 20.4% (0.9 kg) over the stock exhaust, Different thicknesses in the sections ensure perfect protection and reduce overall weight, allowing the added strength created by the design to provide enhanced resilience in the most demanding conditions, It offers an increased response through the entire rev range, with the power and torque levels increased by an extra 1.8 kW (2.4 hp) at 10,600 rpm on the in-house dyno and 1.5 Nm at 10,500 rpm in back-to-back tests as recorded against a standard stock exhaust system, Developed for use on closed-course competition circuits only, it is a simple plug-and-play operation to install, with no remapping needed
