Yoshimura RS-4 Slip-On Muffler for the KTM 790 / 890 Adventure & Husqvarna Norden 901

Yoshimura started off by developing their Works Finish RS-4 muffler profile to compliment the KTM's power delivery. In response, the bike saw an increase of 5.5% in max HP, and 4.7% in max torque. To add to the aesthetics and protection they included a carbon heal guard. 

Power gains, weight savings and an incredible sounding exhaust delivered in a durable package that is developed and manufactured in the USA.
