Great
Worked great, bought a ‘06 wr250f with an aftermarket pipe and no spark arrestor. Changed the jets and it still ran wonky, added the spark arrestor and the back pressure seems to help her run smooth. Also tend to ride in dry forest fire areas.
Fit perfectly and came with all necessary hardware.

Questions
Will this insert also quiet the muffler down? Is it a quiet core insert as well as a spark arrestor?
Yes, this will provide a slight decrease in the noise of the muffler without affecting horsepower
