works great, really makes it quieter, and still runs great.

It’s OK, but didn’t help noise level that much.

This was able to be adapted to a non stock exhaust and did work with modifications but made it more difficult.

DOES NOT FIT MASSIMO ESU-500 AS ADVERTISED! Don't waste your time and money crawling underneath and unbolting anything. It doesn't fit nor does it reduce any noise from the exhaust. The flip up Brackets are about an inch from the Frame where it needs to bolt up. ***Note*** If you try and bend the Brackets over to fit they still won't reach as they'll be too short. We didn't attempt it as Geometry tells us all that this is the case. We own a Custom Fab Shop and bolted this up anyway to the back of the Muffler just to see if it was worth modifying, which we could've easily done. It also didn't make any difference on an actual Decibel Meter. Sorry Silent Rider!

My model differed from the adapter that came with the muffler I ordered and they sized it and sent me the correct one no questions askedThe muffler itself installed easily and cuts the exhaust noise down quite a bitI would definitely recommend this product

thought it would be more quiet and when you tilt the bed it hits muffler--eventually it will jar or loosen the muffler

Working great on 2007 Yamaha rhino 660Lot quieter

There is a difference between engine and exhaust noise with the SXS. I was not expecting a miracle with the silencer because the bulk of the noise comes from sitting on top of the engine. This product does quiet the exhaust at idle but I was hoping for a little more reduction at higher speeds. I am not upset that I bought the silent rider but I don't know that I would do it again. Probably a good product for hunters.
