Tips - Exhaust Pipes, Catalytic Converter, Mufflers

• 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.
