Yoshimura racing exhaust systems

Traditionally associated with the Suzuki GSX-R American Superbike race teams, Yoshimura are now offering a massive range of race-developed exhaust systems and slip-ons for all popular sports bikes and dirt bikes.

Lightweight, 20 gauge, large diameter, equal length header tubes connect into a 4-1 or 4-2-1 collector for maximum gas flow. Duplex race systems have small canisters attached to the header for more instant power delivery when getting back on the gas when exiting a corner under race conditions. Exhaust gases are released through an unrestrictive straight-core baffle.

Race Only Slip-ons
Simple bolt-on replacement silencers that significantly reduce weight, while adding a slight increase in performance. Re-jetting or re-mapping is often required. All systems listed here have stainless steel headers and/or link pipes unless otherwise mentioned.

RS-3 slip-ons and full systems feature an oval silencer. Zyclone silencers are quieter than race, but still not road legal. Duplex headers include the cross-over canisters on the header pipes.

Please contact us for pricing information.

All these pipes and slip-on cans are for racing use only.

All Yoshimura systems will increase power output of your motorcycle over stock systems, but to gain the most benefit we recommend that the system is installed by one of our expert fitters and the bike is then checked on our dyno.
