Yoshimura RS9-T Stainless Full Exhaust System for the 2022+ Honda Grom


One of the most iconic exhausts systems is now available for your 2022 Grom!

We have ECU flashes available for this exhaust system ready to go as well!

"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!"
