Stock 04 exhaust insert needed

Hi gang,

Anybody still have the stock exhaust insert for a 2004 wr450 that they would be willing to part with? Getting complaints from the neighbors when I run the bike without one.

If no one here has one I guess I will look at the GYTR and Pro Moto Billet insert, so any comments about either of those inserts?


Spend the money on the billet insert, it does not take away any power where as the stock insert does.


I've got my stock insert and I'll sell it to you cheap, just pm me.

Just shove a potato in the tailpipe. :applause: The stock insert is about as quiet, and breathes about as well. You'd be better off spending the money for the GYTR insert (That's what I've got and it isn't too loud).
