Why Choose Yoshimura Exhausts

Proven Racing Heritage

Since 1954, Yoshimura has dominated motorcycle racing across MotoGP, World Superbike, and AMA championships. Every street exhaust incorporates technology developed and proven on the world's most demanding racetracks. When you choose Yoshimura, you're choosing the same engineering that powers factory race teams to victory.

Street Legal Performance

Yoshimura's Street Series exhausts deliver race-inspired performance while maintaining EPA compliance and street legality in all 50 states. These systems feature qualified manufacturer declared "replacement part" status, meaning they don't tamper with emissions controls and meet federal requirements for sound and emissions. Get the performance you want without compromising legality.

Trusted Quality & Engineering

Every Yoshimura exhaust undergoes rigorous dyno testing to verify claimed performance gains. Premium materials including stainless steel, titanium, and carbon fiber ensure durability and long-term performance. Yoshimura's commitment to quality means precise fitment, reliable construction, and exhausts that perform as promised—backed by comprehensive warranty coverage.

Yoshimura Product Lines

AT2 Street Series

The AT2 series represents Yoshimura's street-legal performance solutions. Featuring slip-on designs that bolt directly to stock headers, AT2 exhausts deliver measurable horsepower and torque gains without requiring ECU tuning. EPA-compliant construction with appropriate noise labeling makes these systems legal for street use while providing the aggressive sound and enhanced throttle response riders demand.

R-77 Series

Yoshimura's iconic R-77 exhaust combines race-proven design with street versatility. The distinctive three-quarter system layout optimizes exhaust flow for maximum mid-range and top-end power. Available in stainless steel, titanium, and carbon fiber configurations, R-77 systems offer exceptional weight savings and performance gains across sport bikes and naked machines.

RS Series

The RS series delivers pure racing performance for track-focused riders. These systems maximize power output through optimized header design and racing-specification mufflers. While designed primarily for competition use, RS exhausts showcase Yoshimura's uncompromising approach to performance engineering.

Works Finish Technology

Select Yoshimura exhausts feature exclusive Works Finish—a heat-reactive coating that develops unique coloration after heat cycling, similar to the titanium components used on factory race bikes. This contemporary satin/matte finish offers increased fatigue strength, superior scratch resistance, and distinctive aesthetics that set Yoshimura apart from conventional stainless finishes.

Available for Multiple Brands

Our Yoshimura collection includes exhausts engineered for leading motorcycle manufacturers including Yamaha, Kawasaki, Suzuki, and CF Moto. Each system is specifically designed for precise fitment and optimal performance on its intended application—no universal adapters or compromised engineering. Use our fitment filters to find the perfect Yoshimura exhaust for your specific year, make, and model.

Common Questions About Yoshimura Exhausts

Are Yoshimura exhausts street legal?

Yoshimura Street Series exhausts are EPA-compliant and street legal in all 50 states. These systems carry qualified manufacturer declared "replacement part" status, meaning they don't require tampering with your motorcycle's emissions control system. They meet federal tail-pipe emissions standards and include appropriate EPA noise labeling. Race series exhausts (RS, Alpha, etc.) are designed for closed-course competition use only.

Do Yoshimura exhausts require tuning?

Most Yoshimura slip-on exhausts work with stock ECU mapping and don't require tuning to deliver performance gains. Full systems (complete header and muffler replacements) may benefit from ECU tuning to maximize performance and optimize fuel delivery, though they typically function well with stock mapping. Check specific product descriptions for tuning recommendations.

What performance gains can I expect?

Performance gains vary by motorcycle model and exhaust system. Yoshimura dyno-tests every exhaust application and provides verified horsepower and torque data. Typical slip-on systems deliver 3-8% horsepower increases and 5-12% torque improvements, while full systems can achieve 8-15% power gains. Enhanced throttle response and improved sound are universal benefits across all applications.

What's included with Yoshimura exhausts?

All Yoshimura exhausts include the muffler assembly, necessary mounting hardware (clamps, bolts, brackets), and detailed installation instructions. Most slip-on systems install in 20-45 minutes with basic hand tools. Full systems may include mid-pipes, headers, and additional components depending on the specific application. Every exhaust is backed by Yoshimura's 1-year limited warranty against defects in workmanship and materials.

How do I maintain my Yoshimura exhaust?

Yoshimura exhausts require minimal maintenance. Clean with mild motorcycle soap and water—avoid abrasive cleaners. Stainless steel systems can be polished periodically to maintain luster (except Works Finish, which should never be polished). Carbon fiber components require special care—keep mounting hardware tight and avoid chemical contact. Yoshimura recommends repacking mufflers annually to maintain optimal sound and performance characteristics.

What warranty does Yoshimura provide?

All Yoshimura exhausts carry a 1-year limited warranty against defects in workmanship and materials. This warranty covers the original purchaser and requires proof of purchase. Damage from abuse, improper installation, modifications, or lack of maintenance is not covered. Yoshimura offers refurbishment services for exhausts requiring repacking or repair, with typical 3-5 day turnaround plus transit time.
