250-500cc broken exhaust bracket 2009 wr300

I know this is not a rare problem, but i couldn't figure out search terms that would find any info, so here's a new thread. I've only ridden the bike a few months, so it only has 103 hrs and no real tipovers. it does have a lot of hard riding in whoops and chop and rocks tho. The rear-most exhaust bracket broke off of the subframe. I have a local welder guy who has fixed 6 frame brackets on ktms for me, and he can apparently weld aluminum too, so i'm going to run it by there tomorrow. is it worth laying down a bead or 2 to strengthen the forward mount too, or is it usually only the rear one that breaks? Any advice or magic tricks to make this less likely in the future? How much are subframes?


thanks.

Perhaps an overtightened endcan holder to bracket might cause this? It happened to my wr125 before...

Is your tire hitting it?

My tire used to hit my stock silencer. Once I swapped it for the PC silencer the problem went away. I never broke a silencer mount, but I can surely see it happening.
