Exhaust System Inspection
•
Before removing the exhaust system, check for signs of
leakage at the exhaust pipe gasket in the cylinder head
and at the muffler clamp.
If there are signs of leakage around the exhaust pipe gas-
ket, it should be replaced. If the muffler-to-exhaust pipe
joint leaks, tighten the clamp.
•
Remove the exhaust pipe and muffler (see Muffler and
Exhaust Pipe Removal).
•
Inspect the gasket for damage and signs of leakage.
If the gasket is damaged or has been leaking, replace it.
•
Check the exhaust pipe and muffler for dents, cracks, rust
and holes.
If the exhaust pipe or muffler is damaged or has holes, it
should be replaced for best performance and least noise.
