CAUTION
When removing the mufflers from the housing, DO NOT use the turbine as leverage or pry the
mufflers out of the housing. If the turbine is pulled while removing the mufflers or the mufflers are
pried out of the housing, rather than pulled straight out, damage to the VELA may result.
To remove the left side muffler, using needle nose pliers, firmly grasp the metal grid inside the
housing and pull the muffler straight out of the housing assembly using a clockwise twisting motion.

NOTE
Only the Right side muffler has a filter attached, the Left side is a muffler only.

housing to the correct depth. .
NOTE
Some of the muffler/filters may be larger in diameter than others, do not force these into the
housing, instead squeeze the muffler for a minute and then quickly install the muffler into the
housing using the muffler filter insertion tool .
