fmf titanium 4, please help need SA info + quiet info

I bought a bike with a FMF Titanium pipe, header and mid pipe already installed. Seems to work well. I'm getting ready to go to Moab Utah to ride some trails, and know that per federal law I need to make my bike quiet and put in a spark arrestor.

I measured the can that I have and the tube itself is 14" long. I was wondering if anyone knows what I need and where I can get it cheap?

The FMF site doesn't provide many pictures for what I"m looking for so I wondered if someone may have some information that would help me (maybe even experience).

Thanks for you help.


If it's a reasonably recent Ti4, FMF should list a spark arrester insert for it. I don't know about the sound level, though.
