Features:
- 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
