TOCE PERFORMANCE / YAMAHA YZF-R9 / 2025–2027
RACE-BRED CP3.
UNMISTAKABLE TOCE SOUND.
Bring Yamaha's 890cc CP3-powered YZF-R9 to life with the Toce Performance Razor Tip Full Exhaust System. Featuring precision mandrel-bent stainless steel headers, a compact baffled Razor Tip muffler, and an application-specific oxygen sensor relocation kit, this complete exhaust delivers aggressive triple-cylinder sound, reduced exhaust bulk, and track-inspired styling.
Engineered for the Yamaha YZF-R9
The Yamaha YZF-R9 combines a responsive 890cc CP3 inline-three engine with a purpose-built supersport chassis, aerodynamic bodywork, and advanced electronics.
The Toce Razor Tip Full Exhaust System is designed specifically for the R9, replacing the factory header and muffler arrangement with a complete stainless steel performance exhaust.
The compact Razor Tip muffler gives the motorcycle an aggressive, race-inspired appearance while allowing the CP3 engine's distinctive three-cylinder sound to come forward.
This is an R9-specific system, not a repackaged MT-09 or XSR900 exhaust.
Complete Stainless Steel Full Exhaust
This is a complete header-to-muffler replacement, not a slip-on or decat-only system.
Precision mandrel-bent stainless steel headers route exhaust gases from the CP3 engine into the signature Razor Tip muffler, creating a complete performance-oriented exhaust assembly.
The system includes an oxygen sensor relocation kit to position the factory sensor appropriately and a dedicated mounting bracket for the canister.
Designed around the Yamaha R9 chassis, the system is compatible with OEM fairings and factory mounting points.
Precision mandrel-bent construction developed for the 890cc CP3 engine.
Compact angular canister with baffled construction and aggressive triple-cylinder sound.
Included hardware positions the oxygen sensor appropriately for the exhaust layout.
Application-specific mounting bracket designed for the Yamaha R9 chassis.
Performance-Oriented CP3 Engineering
The Razor Tip Full Exhaust is developed to improve exhaust flow, reduce unnecessary exhaust bulk, and complement the R9's high-revving three-cylinder performance.
The complete stainless steel header assembly and compact muffler replace the restrictive factory exhaust arrangement with a more direct performance-oriented layout.
Toce recommends ECU flashing or tuning for optimal performance with this system and specifically recommends 2 Wheel Dyno Works for Yamaha R9 calibration.
Performance results depend on engine condition, intake configuration, and ECU calibration. Specific horsepower, torque, and weight-reduction figures are not published on the current product listing.
For optimal performance with the Razor Tip Full Exhaust, Toce recommends professional ECU calibration through 2 Wheel Dyno Works. Exhaust-only horsepower and torque gains are not specified.
Unmistakable Three-Cylinder Sound
Yamaha's CP3 engine is known for its distinctive exhaust pulse, strong midrange character, and aggressive sound under acceleration.
The Razor Tip Full Exhaust delivers a deeper, throatier, more aggressive note than the factory system, with a compact muffler that complements the R9's supersport styling.
The muffler uses a 304 stainless steel spiral-welded perforated baffle assembly and ISW acoustic packing rather than an empty, unbaffled shell.
An optional secondary Razor decibel killer is available separately for additional sound attenuation.
Polished or Full Stealth Black
The R9 Razor Tip Full Exhaust is offered with polished stainless steel headers or an optional Full Stealth Black finish.
The polished configuration highlights the stainless steel header construction, while the Stealth option creates a darker, more aggressive appearance that complements the R9's bodywork.
Exposed stainless steel header appearance with the signature Razor Tip muffler.
Optional black-coated configuration for a darker, track-inspired appearance.
Premium Materials. American Manufacturing.
The Razor Tip muffler incorporates chemically certified 6061-T6 and 6063 aircraft-grade aluminum components, a 304 stainless steel spiral-welded perforated baffle assembly, and ISW acoustic packing.
The complete system features precision mandrel-bent stainless steel headers and application-specific mounting components.
Toce manufactures its exhaust systems using in-house designed and CNC-machined components, dedicated production fixtures, and hand-welded assembly in Manchester, Connecticut, USA.
Each exhaust is designed around its intended motorcycle rather than assembled from universal mufflers and generic mounting clamps.
