Yoshimura RS-12 Evo Exhuast System Honda CRF450R / CRF450RX

The 2027 Honda CRF450R is already making waves as one of the best 450s ever produced, boasting a redesigned chassis, airbox, and ECU. Yoshimura's RS-12evo Signature Series SS/TI Exhaust System takes that elite foundation and pushes it to the factory level. Engineered by the minds that know the CRF450R best, this system was developed alongside Team Honda HRC race teams in the USA, Europe, and Japan to deliver maximum power, torque, and rideability.

Formerly known as the Hybrid system, the new SS/TI setup pairs a hydroformed titanium muffler with a stainless steel header to give you the exact same power profile as the premier full-titanium RS-12evo system, but at a more accessible price point. The entire package remains lighter than the stock exhaust and utilizes advanced hydroforming and strategic resonators to fine-tune power delivery while reducing noise.

Features:

• All-new RS-12evo carbon fiber end cap pushes styling and function to the next level
• Hydroformed titanium muffler maximizes spatial efficiency near the airbox, subframe, and shock for a perfectly nested fit with stock side panels
• Two-piece muffler resonator fine-tunes power delivery, reduces decibel output, and improves overall durability
• Patent-pending Precision Taper Fit system allows for fast, easy removal and installation of sound inserts and spark arrestors
• Hydroformed header primary exactly matches the oval exhaust port with a perfectly smooth transition to round, reducing welded connections for better fitment and durability
• HRC-developed header resonator maximizes power across the entire RPM spectrum while enhancing throttle connectivity
• Cast manifold increases system strength and makes installation and removal easier
• Overall weight is lighter than the OEM exhaust system
• Designed, developed, and manufactured in the USA
