550 Grizzly 2011

matthew in PA – Machine this part was bought for: 2011 YAMAHA GRIZZLY 700 4x4

Comments On Feb 01, 2013:This worked great on my 2011 grizzly 550. The sites does not show it working with my quad only the 700 and 660, but the oem exhaust for the 550 and 700 are the exact same.

Good exhaust

Kyle in TX

Comments On Dec 12, 2010:Installed this exhaust on my 2004 Yamaha Grizzly 660 after a seam on the factory muffler blew apart. Super easy to install. Only improved performance slightly, but the sound is certainly nice. The exhaust looked great at first, but unfortunately it only took a couple of months for the finish to tarnish.

feel the difference from the stock pipe.


Comments On Nov 18, 2009:I have a 2007 yamaha grizzly 660. was looking for that little bit more power without the noise. the fmf is only 5 desibles louder. my friends ride behind me and said the noise level did not seem louder than stock. i put a fmf stage 1 jet kit in it, a pilot jet 5 sizes bigger and a K&N filter with the aluminum adaptor. the stock filter is horrible. the power gain is noticeable and the engine is snappier. you dont have to change any packing. the only complaint is the lock nut for your header clamp. get one that has no teflon insert. it melts away, then vibrated off. the pipe will slide off and get realy loud. after putting a all metal lock nut it cured the problem. also using red locktite too. i feel the pipe did the job, with its other components that are manditory when putting on a pipe. jetting is important so do it right if you dont know how, pay someone that knows what they are doing.

Lewis in UT

Comments On Aug 31, 2009:This pipe isn't worth the money. Had carb rejeted,ran it for 4 rides, then switched back to stock muffler and the stock muffler worked better. keep your money to spend on something that will actually work for you. Rocky Mountain was as always great on shipping

Love my new pipe

Brannon in SC

Comments On Mar 11, 2008:Put this pipe on a Yamaha Bruin 350 4x4. It sounds and performs great and cleans up nice after mud has dried on the pipe. No more back pressure in my atv after the pipe was installed. I also added a jet kit with k&n air filter which is very nice!

FMF Powerline exhaust


Comments On Nov 20, 2007:Purchased for 2005 Honda Rancher 400AT. Quality is very good and no service ever required.
Performance is good, but have seen better results with a Mega Max pipe on a buddies Rancher 350. Could be the difference in machines.
Recommend adding a K&N with this pipe. No re-jetting required.
