Introducing Bristol Core high performance muffler packing.  This is the longest lasting muffler repack kit available! Durability was our goal when we began developing Spec 30 Packing. The traditional materials used to repack mufflers just don't hold up to the heat produced by modern four stroke engines. Repacking your silencer with Bristol Core muffler packing can increase performance, lower noise and extend the life of your silencer.

Increasing Performance with Bristol Core
Bike and exhaust manufactures tune the exhaust system and engine based upon a freshly packed silencer.  Best exhaust performance is achieved when muffler packing is new and properly installed.
- Throttle response remains crisp
- Power output is maximized
- Fuel efficiency is maximized

Lower Noise with Bristol Core
When the silencer is freshly packed sound waves are better absorbed.  Worn packing can have holes or be completely blown out thereby allowing exhaust sound waves to pass through the silencer and not be absorbed by the packing material.
- Noise reduction and exhaust tone are maintained.
- Vibration absorption and baffle support.

Extend the life of your silencer with Bristol Core
When the muffler packing is worn or blown out exhaust temperatures can reach extreme heights which can deform or damage silencers.  Four stroke exhaust systems can see very high temperatures at the silencer which can burn or deform silencer inserts, cans or end-caps if the muffler packing is worn, damaged or blown out.

FEATURES:
- Main pillow is filled with 450 grams of Spec 30 Packing material.
- Pillow designed with adhesive tape flap for keeping it rolled tight during installation.
- Kit contains two cap stuffer pillows.
- Easy to follow installation instructions.
- Longest lasting muffler packing material available.

Bristol Core is the longest lasting muffler repack kit available! Durability was our goal when we began developing Spec 30 Packing. The traditional materials used to repack mufflers just don't hold up to the heat produced by modern four stroke engines.

Most modern engines and especially those with EFI, produce exhaust gas temperatures that exceed the temperature limits of traditional packing. Once a fiber's temperature limit has been passed, it becomes brittle and breaks down into particles small enough to be "blown out" of the muffler. Spec 30 is different because it maintains it's strength in temperatures up to 1400F.

Whether you're maintaining the muffler on a motocross bike, an ATV or a utility vehicle, Spec 30 will last longer than the competition. There are many benefits to keeping a muffler completely packed and flowing as it was designed to. Among them are:

- Throttle response remains crisp.
- Power output is maximized.
- Fuel efficiency is maximized.
- Noise reduction and exhaust tone are maintained.
- Vibration absorption and baffle support.

Our new Spec 30 Universal Pillow Kit delivers our high performance Spec 30 Packing material in pillow that is easy to install. The pillow is compressed with stitches which release within a couple minutes of being exposed to exhaust heat. In compressed form, it can be cut to length easily and rolled around the mufflers core. Once the compression stitches release, the Spec 30 expands filling the muffler cavity uniformly for maximum durability.

Don't waste your money and time repacking with a material that you'll need to replace any sooner than you have to!
