PO put yz exhaust on my '07 wr450 and its way too loud. Want to replace with a slip on, but I'm not sure if the header is stock or also from a yz.
Is there some way to identify one from the other?

It is almost certainly the YZ header pipe because the stock 2007 WR header is a smaller diameter and the YZ muffler will not fit

I believe the outside dia of a YZ headpipe is 1 5/8

Yz muffler needs a yz header.

Thanks for the replies, will order for a yz. Would the yz header be for the same model year ('07)? It bolts up to my wr with no obvious mods.
