SPARK ARRESTOR
1. USFS Approved Spark arrestors are included inside the
mufflers of every DMC Afterburner Exhaust.
2. To access your Spark Arrestor, simply remove the 4 screws
from the endcap.
MAINTENANCE
Please allow exhaust system to cool prior to washing or repair.
DMC recommends using a mild soap such as dish detergent
and water to wash your exhaust system. Also, you should
not allow water to enter the muffler outlet while washing your
vehicle. As we all know, sound is a major issue, which can
effect whether or not we continue to enjoy our sport without
offending others. Also, your system performs best and will last
longer when the mufflers are properly maintained. Repacking
your silencer depends on the type of driving and the amount of
hours on the engine. Your ears are the best guide to knowing
when to repack, but as a rule, every 20-30 hours of hard
driving is a good guideline for inspection and a Muffler Repack
kit if necessary. If and when it is time to repack, please use
DMC Afterburner Repack Kits as they were designed and tested
to provide the ease of installation and top performance. To keep
your spark arrestor clean, you can clean it out by using a soft
bristled brush and soapy water. Spark arrestors only need to be
replaced if the screen is blocked or torn.
