    Comments about Yoshimura - Comp Series RS-4 Slip On (Stainless):

    I purchased this for my 2011 rmz250, and I'm really happy I did, the slip on looks and sounds great, the picture doesn't do it justice as the thing is really shiny. It fitted like a glove. I was surprised it was a bit heavier than stock but on the whole it's worth it. I found a big improvement in midrange running the standard map, and sounds like it means business. A tip would be make sure its nice and clean before you fire it up as finger prints will leave their mark.

      Great product! Looks really good on my 08 YZ250F. Sounds a lot meaner as well and can tell a big difference in power.

          So happy with this product.
          Got it for my RMZ250 2011 adds awsome top end power very crisp, without loosing any bottom end. And helps with the overrev.

          Sounds great and helps the bike run how it should.
          Just don't like the fact its only riveted together, no screw to open and change the packing.
