How long did your exhaust packing last? (FMF)

I checked on mine at 6k when I was messing with the quiet core thing and it looked ok. Now I'm at 11k though. Just wondering if its almost time. Its pretty friggen loud even with the quiet core, but always has been lol.

I'll be doing mine in the next month or two. Pics will follow.

I guess I've got about 7000-8000 miles on mine.

here's one <-- 15,000 miles

I randomly decided to repack mine last summer with 2500 miles on it and the top 6" near the tip where all blown out. My bike only has 3700 miles on it which is alot less than alot of folks on here but i pretty much only use this bike off road since I bought a street bike. living in CT also limits most of my rides to trailering it to the trails since most places are at least 45 min away I dont want to ruin my knobbies commuting to the woods.
