Exaust Repacking?

Recommended Posts

The muffler/silencer is usually filled with a heat proof batting, designed to absorb sound. Over time, it deteriorates (and on a 2S) absorb oils. So it 'wears out' and periodically needs to be replaced, typically every 20 hours of run time or so for optimum sound absorption qualities.

how is it done, and is it expensive?

All depends.

 

Is the muffler/silencer in good physical condition?

Is the end cap riveted or bolted on? If it is rivent, you'll have to properly drill out the rivets and have the correct replacements ones on hand as well as a rivet gun. If it is bolted on, are the bolts seized?

How handy/capable are you with tools?

Have you read up on repacking the muffle/silencer from the manufacturers instruction sheet?

 

Cost of material is from as low as $10 to as high as $30. Some exhaust manufacturers offer a repacking service, you send them your muffler/silencer and the service it and send it back. Of course, that is the most expensive way to go as well as causing a lot of downtime.

Easy. 

 

Pull the exhaust apart.  Clean everything metal with a wire brush.  I recommend wearing old Mechanix gloves or something, the metal bits inside are sharp and pointy and fiberglass from the packing ... sucks.

Follow the directions in the packing or muffler... pretty simple though.  Wrap the fiberglass packing over the core, keep it on there with some baling wire, and reassemble.
