• To assist with weight reduction, the internal silencer components and the link pipe are manufactured with titanium.
• This competition system is supplied with a race baffle insert for when racing noise standards are enforced. This system does not meet ADR 83:00 noise standards and is not recommended for street use.
• There is provision for mounting an Exhaust sensor or blank off plug when required.
