Yoshimura RS-9T Street Stainless Slip-On Exhaust with Stainless Muffler | Honda Grom 2022-2026 | Works Finish

The Yoshimura RS-9T Street Stainless Slip-On Exhaust is a bolt-on muffler for the 2022-2026 Honda Grom, built with a stainless steel muffler sleeve and a carbon fiber end cap, finished in Yoshimura's exclusive Works Finish, and mounting directly to the stock header.

The Grom's factory exhaust is heavily restricted to meet noise and emissions targets on a 125cc single, so a muffler change frees up proportionally more than the same swap would on a large bike. The RS-9T is Yoshimura's compact canister developed specifically for minibike packaging, where there is very little room to fit a muffler that still works properly.

The Works Finish is the visual signature: rather than a fixed coating, it develops its colour through the system's first heat cycles on the motorcycle, ending up close in appearance to the titanium works components on Yoshimura's factory race bikes. As a Street Series slip-on it installs in minutes without disturbing the emissions control system.
