Exhaust system

Description - Exhaust Pipes, Catalytic Converter, Mufflers

Occasionally the exhaust system will develop an annoying rattle.
Catalytic converters must not be disposed of as regular scrap. The catalytic converter contains valuable rare earth metals, which can be recycled.

Edit required.

To investigate an annoying rattle jack the vehicle up and place on stands. Tap the exhaust system with a rubber mallet while listening for the rattle. It is often a broken strap or bracket making the noise.

Edit required.

When reassembling a new or repaired exhaust system apply high temperature anti-seize copper grease to all the gaskets, seal rings, flange surfaces, and bolt threads. You will really appreciate having done this next time the system has to come apart.
Also cover all exposed bolt threads with silicon to prevent corrosion. The silicon is easily peeled off before undoing the next time. If you have previously used the copper anti-seize grease you will be able to undo the nut by hand.
