Exhaust System: Service and Repair

Notes:
^ Exhaust manifold, removing and installing
^ After working on the exhaust system ensure that the system is not under stress, and that it has sufficient clearance from the bodywork. If necessary, loosen double and single clamps and align muffler and exhaust pipe so that sufficient clearance is maintained to the bodywork and the support rings are evenly loaded.
^ Replace self-locking nuts.
