Will a 07 WR450 Exhaust fit a YZ426F 02

13 posts in this topic

Hi, I was wondering if this type of exhaust (muffler) will fit on my 426 2002. I think its from a WR450 07 couse i googled the YMS400B part number that its written on it. I want to change mine couse its really banged up.

So i bought the exhaust and it fits perfectly. No modifications, no remaking. Just switched the grephite gaskets from the old one to the new and everything fitted perfectly. The sound is completley different. But now I have the feeling that the bike has less power but im not sure. Maybe I think this becouse its less noisy. Is it posible to realy lose power from somethnig with the new exhaust?

Really?

So it's just a muffler, not the full exhaust then.

I was unable to find a 426 header that fit from another year

Would the yz426 be too big for second bike? I have a ttr230 right now and it's just not close to enough power.

 

Please don't piggyback on someone elses post

 

This question should be posted in the 'what bike?' forum

yes. withouth the header. i left the original one. i changed it becouse the old owner has fliped the bike and it was all bent up and noisy. it was just a hollow aluminium pipe. i think it was not the original one. now the new one is perfect. it has a very melow sound and got rid of the bangy metal sound. got rid of the hissing from missing hex screws. but im still not sure if it has lost some power. maybe i just cant get used to it.

If the pipe is stock it will reduce power. 

You can add a 'gytr' tip to the pipe that will remove the 'pea shooter' plug in the end.
