Looks good, sounds great, and was a breeze to install. The silencer is a little cocked, but maybe I tightened the front bolts too soon, not sure, and too lazy to try and fix it, still looks great!

This exhaust kit is amazing if you want better performance, but not an obnoxiously loud sound. It’s definitely gives a beefier, deeper and louder sound, but nothing overboard. Install was super easy and fast with just a basic socket set. Definitely order an exhaust pipe gasket when ordering this kit. I installed this on a new 2023 with less than 50 miles on it and found out that my Grom didn’t even have a gasket from the factory!

Ride a 2021 R1 Liter-bike but purchased a new 2022 Honda Grom 125 as a project bike and local streets toy. The Yoshimura RS-9T was one of the first mods added and it makes all the difference in performance and styling. “Get envious looks whenever bleeping the throttle slow-cruising thru the outside malls/restaurants areas in West Las Vegas!”

This exhaust is worth the money. It sounds great! It adds power and it saves weight. The quality is second to none.
