Has anybody done this?

I just brought my YZ450F home. Holy buckets, its loud! I figure I could find stock WR muffler somebody has taken off for a good deal, if it would work ok.

i think it will fit, the yz and wr use the same aftermarket exhaust part numbers. it will cork it up though and you might need to re jet it.

wr muffler is a little more restrictive..

guys put yz mufflers on their wr's to get more hosepower.

Don't put a WR can on your YZ, a quiet pipe will give better performance and weigh less. Nearly everyone offers them now, the ones I seem to hear the most good about are the FMF's and Leo Vince's.
OT- where in OR are ya?

Don't use the Wr pipe, it is way to restrictive. I just took one off of mine and used the yzf can.

it will be quieter but have way less power, it has a AIS system i believe, i think that lets air into it somehow to decrease the emissions. someone please correct me if im wrong lol.

You're wrong. :excuseme: The WR450 has an AIS, but it isn't an integral part of the exhaust system.

I'm really not too worried about losing a couple ponies on a 450.

It just needs to be more quiet.

I think I might look into a Leo Vince. My buddy has one on his '07 and has passed 96dB sound tests.
