Yoshimura R&D Signature RS-9 Slip-On Exhaust Honda Grom 2015


$462.99 USD 


The same Yoshimura exhaust system 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.
