Muffler Repack Kits

Burns Lightweight mufflers can be packed with high temperature fiberglass, stainless steel scrubble or, for some sizes, both.  Fiberglass is the least expensive, quietest and lightest option and works well in most cases where the muffler is located away from the engine.  For extreme and higher temperature applications, we recommend using stainless steel scrubble. It is more durable than fiberglass, but heavier, more expensive and louder (1-2 dB in most cases). Lead Time Usually in stock and can ship same day. Tips on Ordering Choose fiberglass or scrubble packing, Select size option that matches your application Note that some kits may allow for multiple packings of a muffler. Refer to this LINK for the approx. amount of scrubble needed to fill your muffler.
