Installing A New FMF GYTR Pipe On My Yamaha WR450F: Step-by-Step Guide | Before and After

[@EnduroUK.]

The yzf has a rubber washer on the bottom bolt apparently

[@joshclarke2612]

I have the same bike! I love it! Just got the new fmf blue anodized muffler with the carbon cap for mine!

[@F80mthree]

Did you not use rtv copper max temp gasket maker on the header to seal it? Didn’t hear you mention that at all. Curious if the bike ever had an exhaust leak.

[@koltonfreck]

I haven't had any problems with it so far but will probably use the RTV just to be safe

[@Dom34007]

I’m tryna get a new GYTR FMF for my bike because I looped it and jacked up the FMF GYTR it has on it 😂

[@jdavishornet]

Is this the YZ450f slip on? I want to get one but everything I see is listed for YZ

[@koltonfreck]

Yes this was a slip on for a YZ. Don’t quote me on this but I’m pretty sure 90% of what will fit for a YZ, will fit for a WR besides plastics, gearing, etc.

[@jarrod1687]

Sounds tough

[@chillon2922X]

I got the fmf too. Its very very loud. Way louder than the yz exhaust, and even louder than my fully opened old ducati. Won't bought it again because of that. I think here, even on closed tracks, i could be possible that they send me home because of that.

[@koltonfreck]

It IS loud, however, I did see a much needed improvement in low end torque and really let the bike breathe more. But agreed, not ideal for street use.

[@EnduroUK.]

I’ve just fitted a stock yzf 450 pipe to my 2022 wr 450 and it doesn’t slide down the header as far as the stock wr one I can see yours doesn’t either it does clamp and seal though

[@raynorbarnes4713]

I’ve actually got an exhaust leak where the header meets the slip on

[@F80mthree]

@@raynorbarnes4713you’re supposed to use rtv copper max temp gasket maker to seal the pipe. Doesn’t look like this guy did it either. I made the mistake of not using it as well. Hope this helps.

I don't even got money for a 50cc moped....letalone for a wr450r..... nice tutorial, but, i'll never be able to use it..😢

[@koltonfreck]

Shoot a 50cc moped sounds just as fun

[@koltonfreck]

Thanks for watching sal!

[@sal-x-king]

@@koltonfreck hahaha, ye, no problem, i alwqys watch good vids!

[@jarrod1687]

You can do it bro, don't have a victim complex and grind until you get what you want

[@garethjohnstone8662]

"Always, always wear a helmet!" But not you bro. Lol.

[@koltonfreck]

😅i'm sorry I can't control my 30 year old brother

[@jarrod1687]

In Australia if you're on your learners or RE license doing this will make your bike illegal and uninsured, pathetic country

[@koltonfreck]

That is so messed up...Sorry to hear. The emission laws on motorcycles and recreation vehicles is out of control.

[@JC-vo9th]

The reason it makes the bike not approved is the hp increase, learner approved bikes work on power to weight ratio, uncorking a wr450f alone makes it non approved, all to do with power to weight though, not emissions
