Complete HOMOLOGATED exhaust system. Variable diameter manifolds with integrated compensator and catalyst in the manifolds. Made of stainless steel with titanium silencer and removable DB-killer. Fantastic look, and an improved power delivery of the 3-cylinder Yamaha over the entire rev range. It does not need any remapping of the ECU, the sound is wonderful!
Compatible with Yamaha MT-09 2017-2020 and XSR 900 2017-2019.
