Yoshimura RS-9T Exhaust for Honda Fit – Complete Performance Upgrade

Unleash Your Honda CRF450R/RX’s True Potential

Crafted through intensive collaboration between Yoshimura engineers and American Honda HRC’s racing specialists, the RS-9T Full System redefines performance for serious off-road competitors. By strategically relocating dual mufflers forward beneath side panels, this exhaust achieves unprecedented mass centralization—sharpening handling through technical trails or aggressive motocross corners while optimizing rider control.

Precision-Tuned Performance Highlights

• Race-Proven Validation: Rigorously tested by Honda’s R&D teams in Japan and America’s MX racing squads under extreme track conditions
• Tri-Stage Header: Expands power bandwidth across RPM ranges—ideal for explosive corner exits or sustained high-speed straights
• Dual-Flow Tail Design: Smoothes exhaust turbulence through divided piping, accelerating gas velocity while reducing backpressure
• Forward-Mounted Mufflers: Lowers center gravity by 12% vs stock systems (measured at HRC labs), enhancing flickability in rutted terrain
• High-Capacity Core: Boosts mid-to-top-end torque by 8% (dyno-verified) without sacrificing low-rpm tractability
• Intelligent Acoustics: Increased internal volume cuts noise pollution by 4dB—critical for sound-restricted tracks

Built For Real-World Dominance

Forged entirely in corrosion-resistant stainless steel, this system integrates flawlessly with Honda’s optional electric starter—no modifications needed. Whether battling berms at local MX circuits or pushing limits in hard enduro races, experience heightened throttle response and reduced fatigue from optimized weight distribution.

Competitor Edge: Unlike generic slip-ons requiring ECU remaps, our plug-and-play full system delivers calibrated power gains out-of-the-box while meeting FIM sound standards.

Upgrade your ride’s soul—where championship-level engineering meets trail-conquering reliability.
