Exhaust backbox

A rear silencer, also known as a muffler, an exhaust backbox, silencer of just exhaust silencer, is one of the last parts of the exhaust. When you look at the entire exhaust, the end silencer is attached to the exhaust middle silencer. The silencer is mounted using nuts, bolts and springs. In general an entire exhaust is attached to your car using rubbers.

The exhaust silencer makes sure that the noise escaping from the engine is ´muted´, or ´silenced´, ´muffled´. Additionally, the exhaust silencer also filters exhaust emissions from your car.

Symptoms of a failing exhaust backbox?

There are a number of signs that may indicate that the exhaust backbox needs to be replaced. Symptoms of a bad exhaust silencer are:

Engine is misfiring;
Exhaust is louder than normal;
Condensation from the exhaust pipes;
Loss of engine power;
Smoke from places other than the silencer;

Please note that rust can occur in several places of your exhaust, because of several causes. Think of exposure to salt, albeit from roads during the winter or saltwater in communities near oceans, but other causes are also possible. Such as frequent hits by speed bumps, low clearance potholes, or other impact items, and excessive use or custom fabrication of parts (which are not recommended by the manufacturer).

How to replace an exhaust backbox?

Although a medium difficulty level, you certainly can replace a rear silencer yourself. Always be sure though, to proceed with caution. Because of erosion, it may be hard to disassemble the exhaust silencer. Especially eroded brackets are often difficult to remove. If it proves to be really difficult we recommend removing the silencer with a power tool, such as an angle grinder. Be careful not to damage the other parts under your car though. Finally, got the silencer removed? Assemble the new exhaust backbox to the middle silencer. Check if the suspension rubbers are still in good condition, if these are not up to par, then replace them as well.

Mount the silencer on the middle silencer with sealing paste. Put sealing paste both on the exhaust silencer as well as on the fixing points. Slide the parts over each other and attach the exhaust clamp. Please note not to tighten them completely yet! Turn the silencer so that it does not hang too tight in the suspension rubbers. Does the exhaust back box sits well? Now you can tighten the clamps properly. The last step is to turn on your car and let the engine warm-up. Do not give it any throttle though! Heating up the exhaust system without putting any pressure on it, makes sure that the sealing paste hardens and seals it off perfectly.
