Solutions - Exhaust Pipes, Catalytic Converter, Mufflers
- To investigate an annoying rattle jack the vehicle up and place on stands. (TIP: You may find that When you put the car up on front jack stands only, it will not rattle. One BenzWorld enthusiast Had to level out the back of the car to get the rattle going.)
- Tap the exhaust system with a rubber mallet while listening for the rattle. If you are lucky it is often a broken strap or bracket making the noise. If you are unlucky you may have the dreaded interval issue with the catalytic converters.
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.
