Replacement exhaust system
At 6-cylinder engines a dual system, with dual sections. However, the procedure works the same as in the conventional system. To replace individual components and parts, follow the appropriate sections. Make sure you purchase a new fixture, as well as the stock rubber hangers, gaskets and others. When installing the system components, pay attention to the density of connections.

2. Remove the bottom casing of the engine and gearbox (Fig. 4.102). 3. Disconnect the front section of the flange. 4. Remove the hardware front section (two nuts). 5. Remove the system Bush. Here you will need a helper to support it. 6. Carefully remove the muffler, so as not to damage the catalytic converter. 7. Prior to installation clean the muffler connection of plaque and grime. 8. Threaded connections with a wire brush bristles and grease with special oil. 9. If the system was dismantled completely pre-connect all parts without tightening the connections firmly. 10. Fix the system on hangers before tighten all fasteners. Check that the distance from the exhaust system to other parts of the vehicle is at least 25 mm. 11. Tighten all bolts with a torque of 20 Nm. 12. Take a test drive. The exhaust system must not bump while driving. The rumble and roar indicate constriction connections.
