Yoshimura Race RS-9T Stainless Steel Full Exhaust 22-26 Honda Grom
The third generation Honda Grom. Back in 2013, we couldn't wait for the OG model to arrive on US shores.
With more compression, a 5 speed gearbox and new styling, the latest generation Grom promises even more fun both on the street and at the racetrack... Yoshimura is ready.
For styling, power and clearance we developed our renowned RS-9T to perform on the third gen Grom and the results are incredible, as the new Grom responded like a champ. Our Race Series RS-9T full system adds a staggering 13.9% max HP increase and 14.3% increase in max torque. With performance like that it's safe to say the RS-9T will be on top of the track day podiums around the globe!
We didn't stop there, we designed our RS-9T to offer more ground clearance and lean angle than the previous gen model. For the cherry on top we added a matte carbon fiber end cap and heat shield - Now your new Grom will love you forever!
If your serious - it's only Yoshimura. Proudly made in the USA!
