Note
♦ Do not bend the flexible joint in the front exhaust pipe by more
than 10° because it might otherwise be damaged.
♦ Renew seals, gaskets and self-locking nuts.
♦ After working on the exhaust system, ensure that the system
is not under stress and that there is sufficient clearance to the
bodywork. If necessary, loosen clamp and align silencers and
exhaust pipe so that sufficient clearance is maintained to the
bodywork at all points and the mountings are evenly loaded.
♦ The exhaust manifold and the turbocharger are one compo‐
nent, removing and installing ⇒ page 432 .
