Upgrade the Yamaha R9 with the Akrapovič Racing Line Exhaust System, manufacturer part number and vendor part number S-Y9R21-EET. This competition-focused exhaust system combines a high-grade titanium muffler outer sleeve and end cap with a stainless-steel link pipe and headers. Its premium materials, racing-inspired construction, and distinctive Akrapovič styling provide a performance-oriented alternative to the standard exhaust system while maintaining a clean, purpose-built appearance.
The Akrapovič Racing Line system features a right-side muffler outlet for an aggressive racing look and includes an aluminum muffler bracket for secure installation. The design follows the visual character of Akrapovič exhaust systems developed for Yamaha sport motorcycles, with styling influenced by systems used in World Supersport Championship competition. The system is intended for fitment on the Yamaha R9 and is engineered for closed-course competition circuits rather than public-road use.
This Yamaha R9 exhaust system does not include a catalytic converter or pre-muffler. Because of this race-only configuration, ECU remapping is mandatory after installation to properly calibrate fueling and engine operation. Professional installation and tuning are recommended to help ensure correct fitment and reliable performance. The Akrapovič brand and S-Y9R21-EET part number make this system easy to identify when selecting a dedicated titanium racing exhaust for the Yamaha R9.
