I was thinking of buying a louder and more free flowing exhaust for my wr450, how does the yz one sound and perform? i can get them cheap on ebay (less then 100 bux CAD shipped) compared to like 400 for a fmf one. I also read about their header pipe with an expansion chamber in it similar to a 2stroke, how do they also perform?

Stock Yz pipe sounds awesome very deep and loud.No spark arrestor though but if that is not a concern.You won't be disapointed with a Stock Yz pipe.

the yz pipe is a fantastic cheap upgrade for the wr.

Good power and sound...at a fraction of the price of an aftermarket.

Yeah, and if needed i guess it can work with the fmf header pipes too if you wanted to spend 1/2 the money on upgrading.
