I love my 2010 K1300GT. It brings a smile to my face every time I twist the throttle.

But that muffler is HUGE!

Has anyone replaced it? Options? Opinions?

This is interesting...I have never heard of the requirement to rebuild the silencer every 15,000 miles. Is this normal?

Silencer Packing Maintenance and Replacement

The Delkevic range of silencers utilize thermally and mechanically resistant silencer packing, but due to the nature and function of the silencer itself, over a period of time this packing will deteriorate. A repacking kit container the packing material, stainless steel rivets and high temperature silicon sealant is available directly from Delkevic.

As with any silencer it is necessary to periodically check the integrity of packing material, this can initially be achieved by simply listening to the exhaust tone. If the exhaust tone is uncharacteristically loud or metallic/hollow sounding, most likely the packing needs to be replaced.

The average lifespan of the packing material is dependent upon a number of factors e.g. the load applied, riding style of the user, engine size and configuration etc, for example, a large single or twin cylinder bike will tend to require shorter packing intervals than a 4 cylinder bike of the same displacement. That being said, it is not uncommon for singles and twins to go 10K miles between repacks and 4 cylinders to go 15K or more.

If the packing material is found to have deteriorated, it should be replaced. There will be a drop in engine performance. The deterioration also affects the heat insulation properties protecting the exterior sleeve of the silencer. If repacking is not done there is a high risk of damaging the outer sleeve and also any body panels/fairings that are mounted in close proximity.
