2007 YZ250F Spark Arrestor

Needed this to ride down at Hatfield Mccoy. Mildly changes the sound of bike but barely noticeable. Had to file the screw hole on the arrestor to fit the screw into the original hole that is on the exhaust. No big deal. It fits and it works for intended use.. no complaints.

Very easy to install

bought this spark arrestor insert because I needed it for a trip to the sliver lake sand dunes. It was a very fast install which was one bolt and it worked great all weekend. Good buy

Great purchase

The FMF spark arrestor was very simple to install, just had to unscrew a bolt in the end of the silencer and install the spark arrestor and screw the bolt back on.

Very simple, and it made my bike legal for enduro competition.

Q: Ordered fmf without spark arrestor, can I put it on?
1 month 26 days ago
I just ordered my fmf powercore 4 exhaust for my 02 Honda xr100, but when I ordered it I didn't realize I got the option without the spark arrestor. So I was wondering if I got this would I be able to just add it on myself? And if so how is it installed?

A: Unfortunately this will not fit the FMF Q4 mufflers. It is only designed 4.1 model mufflers. For the Q4, you need the SA quite core insert.
