The Silent Rider ATV Silencer BT-33A compatible with Yamaha Grizzly 550 (09-14) Grizzly 700 (07-13)

Makes the bike a little more quiet..

This thing fit great, and went on in about 15 minutes. The quad is quieter, and now when I run the quad, mostly what I hear is valve and crankshaft noise, not exhaust. Good addition for a hunting quad.

This is just what I needed. It cuts the sound by about 10 dB.

Its junk does not work installed not a tight fit blows by the fittings not a tight fit

Installed this on my 2010 Grizzly 700. This was installed on a stock machine. As you can see it melted my plastic under normal use. If you like melted plastic then by all means buy this silencer.
