FMF Q4 Packing Interval

How many with Q4 have repacked and at what milage interval?

What did packing look like at what milage?

FMF is recommending every 20 hours. Too soon right?

Signs and symptoms you're past due?

My PC4 had an annoying high pitch rasp to it when I did mine...and a repack helped a bunch.
I was kinda unsure until I saw the hole burnt in the packing...and was certainly glad I did it , considering the price.

I think next time I'm wondering, I'll probe around the muffler with a piece of broom stick to my ear looking for obvious bad spots...not sure how well that will work... Keeping in mind it wasnt that difficult or expensive to do.

Meh....I'll be doing mine for the first time in a month or two. (will take pics)
Delaware checks decibel levels at motorcycle inspection time. Mine's due in May.


I've got at least 5000 miles on my original packing. Maybe closer to 7000 miles.


I know it's louder than a new Q4 pipe, but I still don't think it's obnoxiously loud.

Once a year has been working fine for me.
I've been using the Q4 mufflers on 5 bikes, so far.

Moto, just a heads up if you haven't seen ...... High Five had mix up ordering packing from FMF.
