08' YZF complete exhaust with PMB Spark Arrestor End Cap on 07' WR450F. Make sure to use new exhaust gaskets.

The WR pipe is a different diameter then the YZF pipe. You are replacing the complete exhaust or are you asking if the YZF header can be used with the stock tail pipe?

thanks for the info I have a YZF tail pipe and like to put it on my WRF so the engine can "breathe" better :smashpc:

Are you going to plate that baby come Jan 1st? You lucky bastids now have the choice, right?

I also have an 07 WR450 and replaced exhaust with 08 YZ450 complete stock exhaust with the shorty silencer. The YZ head pipe is much bigger in diameter, but it is also titanium and slightly more fragile. Keep the WR one as a back up. I did a JD jet kit, Twin Air filter and cut 15+ lbs along with my YZ exhaust swap and am VERY pleased with the performance...

I've had the Clark 3.6gl for 3 years now on my 07 and love it. Running it at mild rpm's it will go over 100 miles. You have to get an 06 petcock for a short straight fuel line.
