Yoshimura RS9 Street Slip-On Exhaust Honda Grom MSX125

The same Yoshimura exhaust deigned for AMA Pro Supercross and Motorcross competition is now available for the Honda Grom. The RS-9's parallelogram-shaped muffler body increases muffler volume over the stock system, resulting in better throttle response and improved noise cancellation. The uniquely sculpted Carbon Fiber end-caps feature a Tunable Insert System, able to fine-tune power delivery and decibel levels to rider specifications.

Features:

  • Polished 304-L Stainless Steel
  • Lightweight laser cut rivet-bands
  • Premium quality closed-end rivets reinforced 
  • Made In USA

Works and sounds great but with one major issue.
I wanted an exhaust to replace the stock one I have for my Honda Grom to improve safety and coolness of the motorcycle. The Yoshimura exhaust felt way lighter in comparison to the stock exhaust and is definitely saving some weight which is a major performance boost for the Grom. The install was easy and only took ten minutes but I wanted to remove the baffle. I was reading other installs online on how to remove the baffle and it seemed like many other people had the same problem with the baffle. That is the only major issue I have with the product but other than that it is a great exhaust.
