DescriptionThe whole story▼
Akrapovic part P-RPCK391 is the packing material inside the silencer. Akrapovic lists it in its spare-parts file without naming the system it belongs to.
Packing is a wear part. Heat and the pressure pulses of the exhaust gas break the fibre down over time; the exhaust gets louder, and the note turns coarse and hollow. Riders who use the bike on track should reckon with a shorter interval than road use — full throttle at high revs is what wears packing fastest.

Which exhaust system this part belongs to
There is no published system for this number and no diagram in our hands that shows it, so the number itself has to do the work of identification. That is enough if you took it off the old part, off an invoice or out of a parts list. It is not enough if you are working from the motorcycle alone — in that case send us the model and we will look it up.
What Akrapovic publishes for this part
What the manufacturer gives us is the number, the EAN, the category and the price. Photograph, description, material and dimensions are not part of the spare-parts data. We do not guess at a vehicle. Where Akrapovic publishes no assignment and no parts diagram carries the number, we say so rather than put a motorcycle next to the part that might not belong there.
