Have you ever repacked one of these?
I asked FMF how to repack the rear chamber between the turbine and the tailpiece, and they said none needed. I had taken out the old packing from that area, but don't know if that was stock or not.
The FMF guy I asked sounded pretty unsure.
I ended up using their "Performance Packing", and stuffing some in the rear chamber anyways.
Hope it doesn't all blow out on the first run.
The front chamber has a bent tube that fits into the turbine inlet and it was not nearly as simple to pack as the plain-straight tube FMF shows in ther website video. Figures.
