Yoshimura Race Series RS-2 Stainless/Carbon/Stainless Exhaust System - 12121AB251

Not to be outdone, Honda strikes back with the brand-new 2017 version of the pink sized street fun bike the Grom (AKA MSX 125). Yoshimura is ready with performance Race Series system that will make the little fuel injected 4-speed engine come alive! Gone is the weight of that ugly muffler box, so Yoshimura performance can be bolted up!

Fresh off the dyno and out of the fixtures is our proven carbon fiber RS-2 mini system that adds torque, horsepower and less weight. Adorned with our proprietary Works Finish on the systems tubing that will give it that Ti look that's guaranteed to increase head turns by 100%. Add the new Yoshimura Fender Eliminator Kit and you can't go wrong. 

  • Diamond-shaped sleeve
  • Large core and increased muffler packing volume means quieter operation
  • Stainless steel cone end-cap
  • Stainless header and tail-pipe

New Yoshimura Works Finish takes on a unique coloring after it goes through a heat cycle on the motorcycle that looks much like those titanium works components our factory racers use. 

  • Contemporary Satin/Matte finish
  • Uniform heat coloration
  • Increased fatigue strength 
  • Increased scratch and stain resistance

More Fun to Ride
2018 Honda Grom. Tailpipe and muffler were an exact fit. The sound depressor (or whatever they called it) was a tight fit. I had to enlarge the muffler opening a little.
The muffler is loud. My wife said she could hear me at least a quarter mile away. I installed the insert which does cut back on the bark. It is a nice rumble under 4K RPM.
It makes an already fun bike more fun.
