trust me and get an aftermarket exhaust or slip on muffler. You will think why did I even bother with the standard muffler that is so choked up.
Just search this site on "Wr 450 free mods" you'll find everything you need. Once you do the free mods and rejet (I suggest JD kit + pilot jet for your altitude and temp) you'll be amazed. You may not even need an aftermarket exhaust. I took the spark arrester and outlet tip right out of mine to test it and its a little too loud but the power is great so I ordered a Promoto Billet tip. I put the spark arrester back in and I'm happy. You'll also want an extended fuel screw to make adjustments easier.
I think the GYT-R slip on mufflers are the go, I put the new GYT-R propower slip on muffler on my girl's WR250. Oh my god! what a difference it made! They are made to produce more power than the YZ mufflers so you know they work.
