The exhaust works include the exhaust manifold, catalytic convertor, resonator, exhaust pipe, muffler and all associated brackets, hangers and clamps which attach to the body by means of supports and rubber hangers; any damage or improper fixing of these works may result in excessive noise and vibrations. Safety and noise level check should be conducted more frequently, with concern for damaged or bent parts, opened seams, holes, loose connections, excessive corrosion or deterioration, and flaws that permits exhaust fumes to infiltrate the vehicle, and damaged components should be replaced not fixed. It is suggested that application of penetrant oil to the fasteners prior to dismantling can help in freeing the nuts involved and for steering components that are severely rusted welding tools would be required; but in the absence of welders, one may resort to hacksaw to cut off the affected parts or pneumatic chisels; safety glasses/ gloves when wielding these tools should be worn. That is when repairing the exhaust system, one should progress from the rear end to the front, apply penetrating oil on the fasten, replace all gaskets hangers, and clamps, apply anti-seize compound on the thread of the fasteners while replacing them, and make sure that the new parts are not rubbing on under-body causing overheating. Besides, the heat shield should be visually inspected for cracks, dents and missing or loose fasteners from time to time, and in the event the catalytic converter has gone bad, detaching the exhaust system from the catalytic converter, attaching a replacement using new gaskets and tightening new fasteners is the way to go.
