must be renewed.
Ensure rubber bushings no. 19 and sleeve no. 18
are not damaged and are properly installed into
tune pipe support(s).
CAUTION: Damage to bushings and/or sleeve
will eventually cause stress to tuned pipe and
may cause cracking.

on exhaust manifold prior to finalizing pipe instal-
lation.
