Moto Billet
Spark Arrestor
Endcaps and Silent Inserts
The Endo Spark Arrestor Endcap is machined from 6061 billet
aluminum and attaches to the stock exhaust pipe, offering a
reasonably priced alternative to buying an expensive aftermarket
exhaust system. Also available, is an optional, bolt-in,
Silent Insert and Ultra Silent Insert that lowers the sound
level by over 5 db. You may feel a small loss in top end power,
but in sensitive areas, keeping noise down is a must!
