Yoshimura RS-9 Race Exhaust System Honda Grom MSX125

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.

Features:

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

Yoshimura RS-9 Race Exhaust System Honda Grom 2014-2015 5 5 7 7
quality pipe, great performance I got this pipe for my mini racer that is Honda based like the Grom. I had to modify it a bit for the frame but it came out excellent, and flows the 184cc motor like a champion. The sound is nice and I would recommend for any Honda based project June 21, 2016
Great Exhaust This exhaust is perfect for every one including my self need, I can feel the power up and the sound is amazing, loud but not too loud. May 17, 2016
Easy Install, looks and sounds great! This was a great overalll purchase process! The product came extremely fast, the installation was a breeze, and it sounds great on the bike! A drastic difference from the stock exhaust. In the higher revs, there's a big difference. But idling it'seems surprisingly quite. In the end, a great product ordered through a great company. Couldn't be happier! January 29, 2016
Worth the weight alone Looks trick, sounds great, and super light, especially compared to the stock grom pipe! February 1, 2015
Great look, great sound I bought the carbon fiber Yoshimura Full Exhaust and couldn't be happier. It looks great, sounds awesome, and gives me a little extra performance to play with. All in all, it was a great purchase and one that I would make again if I had to. July 28, 2014
Most refined sound from a Grom Couldn't be easier it install! Did it in the entrance way of my 600sq.ft apartment. There are cheaper systems out there but this one looks like a million bucks. And the sound is super refined; not ridiculous. Serious performance gains particularly when you do a ram air intake as well. July 7, 2014
awesome looks fantastic and sounds mean, its not overly loud either Sounds great and is not too loud. The carbon fiber looks fantastic. Delivery was fantastic and fast. June 12, 2014
