I wike it a wot.
Good shit! It did quiet my bike down though. I recommend it to you and all your family members. Even crazy Uncle John. Your old header can be used to make a piccolo. That's about it. Gotta go ride!
Excellent addition to bike. Sounds great, works great. Turns the bike into a proper moto. A little issue with fit due to some bent frame tabs. Didn't notice when installed originally, but once addressed all was good.

Very efficient and easy to use.
It fits, but...
Got this thing with the hope that it would quiet down the Titanium 4 that was on my WR450 when I bought it. I might have dropped a decible or 2, but the pipe was still too darned loud. Later, I bought FMF's FS-Approved Spark Arrestor/Endcap for the T4. The combination of the two did not appreciably reduce the noise level, either.

Great pipe, great sound and power. Perfect fit and the finish is amazing. Get the Fatty Pipe! Awesome price too!
only plug I can find to fit WR450F...don't get the 4 stroke one
I know this states for a 2 stroke exhaust, but I bought the larger one and it was way to big for my 4 stroke WR450F, so I used it for my quadsport z400 4 wheelers. This 2 stroke one actually does fit it on the first knob, with a little bit of twisting. I've tried every plug they have on the site and none fit the WR450F as well or even close to this. Still not an exact perfect fit, but about the only thing out there that will even go in the tiny little stock exhaust hole. DO NOT GET THE 4 STROKE VERSION if you're trying to find one for the WR get this one...its as close as it gets.
