A sandblasted high-grade lightweight titanium muffler outer sleeve with a stainless-steel inner and a carbon-fibre end cap is a sporty addition to this single-cylinder scooter. The muffler features an imprint that creates a dynamic look and provides additional strength for even greater durability. Titanium mounting brackets allow the attachment of the standard stock heatshield.

Lightweight materials create a weight saving of 33,2 % (1,7 kg), compared to a standard stock exhaust system. Power is increased by 0,9 kW (1.2 hp) at 7,500 rpm, with a torque rise of 1.1 Nm at 7,500 rpm, when compared to a BMW C 400 equipped with standard stock exhaust system and tested on the in-house dyno. This product produces a deep and sporty sound, and it is EC/ECE type approved and Euro 5+ compliant. The plug-and-play installation means no remapping is required.
