Always use new gaskets and check that good sealing is
obtained at all connections. Make sure that the exhaust
pipe is not subjected to stresses.
Seal between muffler and engine block
If leakage occurs between the front pipe and the engine,
tighten the botts. If this doesn't help, new gaskets must
be fitted. Tighten the bolts carefully to avoid damaging

Fit new rubber cushions and suspension rings. Make sure
that the exhaust pipes are properly inserted in their con-

or tensions in the exhaust pipes, vibrations may easily de-
velop in the body of the car.
