On YZ's these are fitted and found some on the bay..

As I'd expect would these FMF-type exhausts fit the new WR's too..

as I'm not really fond of these wrap-around exhausts..

 

Just thinking and checking things out, as Im still figuring out what to look for..

 

Thoughts ideas?

I'll check in Holland (where I live too) at the FMF resellers

Thanks for any comments, ideas or links..

I would imagine the YZ pipe would fit the new WR but just speculation.
Most of the same year YZ's with the same frame fit the WR's.

Where will you put the battery if you convert to the behind the shock type pipe?

Why don't you like the pipe?

I don't notice it riding my current yamaha and I love the low end grunt you get from a longer vs shorter pipe. The pipes probably the only part on the bike I have not scratched or dented.

Actually I thought the new 2015-2016 YZ450 pipe was a wrap around and would hopefully fit the 2016 WR450.

Sorry the "none wrap around exhaust" title of the thread lead me to believe that you wanted to ditch the wrap around pipe for something like the 2010-2013 "corkscrew" type pipe.

If the 250f is anything to go by there are little if any gains to be had in the header pipe, a YZ or aftermarket muffler is all that's required.

convert a bit (yes a bit) more weigth to the rear,

I'll be converting it to something similar as on:

to accommodate a set of rear tanks in the (near) future

:thumbsup:

 

Or I might end up making my own curly exhaust header..

I do..

might also lead heat away from the upper front,

as hot air (exhaust pipe heat) rises and above there is the injection system..

(Yamaha had problems with vapor lock due to hot fuel in Dakar on some bikes)

Ok I see where your going now ;) whilst I didn't own one I remember hearing of issues with rear shock absorber oil getting too hot on the early reverse headed machines. Something to think about when trying to build some length into your piping.

On the vapor lock side of things running an external fuel pressure regulator with a return line back to one of the rear tanks so your constantly circulating fuel will help prevent vapor lock. You would need to add a petcock for when you run low on fuel so it feeds back to the main tank. Added complexity that may not be worth it.

Looks interesting, good luck with your build :D
