Refit the horizontal cylinder exhaust pipe (3) and the vertical cylinder exhaust pipe (4) to the respective cylinder heads.
Tighten the flange nuts (9) to the specified torque (Frame torque settings).
Check that the quick-release fasteners (32) are installed on the horizontal cylinder exhaust pipe (3).
Refit the horizontal heat shield (13) securing it with the retaining screws (26), the spacers (25) and the washers (34).
Tighten the screws (26) to the specified torque (Frame torque settings).
Fit the vertical cylinder exhaust pipe (3) to the engine and tighten the screw (15) to the specified torque (Frame torque settings).
Insert the centre exhaust pipe (5) in the horizontal cylinder exhaust pipe (3) and vertical cylinder exhaust pipe (4) and secure with the clamps (16).
Position the clamps as shown in the figure.
Position the clamps (16) so they are flush with the end of the exhaust pipes, or at least so that the notches (B) are not completely uncovered.
Tighten the clamps (16) to the specified torque (Frame torque settings).
Fix the centre exhaust pipe (5) to the fuel tank support bracket (A) by screwing on the nuts (20) and tightening them to the specified torque (Frame torque settings).
Connect the lambda sensors (2) to the main wiring harness (Routing of wiring on frame).
Connect the silencer (8) to the centre exhaust pipe (5) and locate the springs (10).
If removed, install the two rubber bushes (24), positioning on either side of the silencer bracket (27).
Insert the spacer (23) in the silencer support bracket (27).
Move the silencer support brackets so that they rest against the footrest brackets (A).
Insert the screw (30) and, on the opposite side, fit the nut (31).
Tighten the screw (30) to the specified torque (Frame torque settings) while counterholding the nut (30).
Check that the quick-release fasteners (32) are installed on the LH silencer (8).
Refit the LH heat shield (33) securing it with the retaining screws (26), the spacers (25) and the washers (34).
Tighten the screws (26) to the specified torque (Frame torque settings).
Follow the same procedure to refit the RH silencer (7).
