The exhaust back box, or rear silencer, is a key part of your car’s exhaust system. It reduces engine noise, manages exhaust gases, and ensures harmful fumes are safely directed away, all while helping your vehicle meet emissions standards. However, corrosion, exhaust leaks and wear and tear can all damage the exhaust back box, resulting in symptoms that are a sure sign it needs replacing.

A backfire from your car’s engine or exhaust can be alarming but is usually easily fixed. A backfire is an explosion of unburned fuel in the engine or exhaust system, which causes a loud “popping” noise.
A backfire from the engine occurs when unburned fuel in the combustion chamber ignites violently instead of burning steadily. This is often caused by issues with the air-fuel ratio, ignition timing, or buildup of carbon deposits inside the engine.

The exhaust manifold is crucial in ensuring your vehicle performs well and is safe to drive. If your vehicle’s check engine light comes on or you hear unusual noises from the engine, it could be a sign that your exhaust manifold has a problem.

Is it time for a new exhaust? The tailpipe on your car (like all parts) will eventually wear out. As this system works to clarify the noxious gases emanating from the combustion process in the engine, it’s important that it remains in good working order for both the health of your car’s occupants, and our planet.

There are many points of failure on a modern car. From those that can slow it down, to those that can wreck it completely. In recent years, one of the faults that has become more common is a bad EGR valve. And whilst this part has numerous environmental and performance benefits, it is well known for clogging and causing issues within the engine.

Last year the number of catalytic convertor thefts almost doubled. And you don’t have to be the most imaginative person to picture how frustrating it must be to try to start your car in the morning – only to find that this vital piece of the emissions system has been ripped off.
Not only is it an inconvenience, but it could also increase your insurance premiums when you claim for a replacement catalytic convertor – or worse still if you have a very old car, it could put it beyond economic repair. So how can you avoid getting yourself in such a predicament?

Catalytic convertors are an essential car component that works to reduce the amount of harmful emissions that come out of your car’s engine. This metal canister operates as a fixed part of the exhaust system and uses a chemical catalyst to remove pollution from the engine’s exhaust gasses making them dramatically less harmful.

Obviously it is normal for a little smoke to come out of your exhaust pipe, which is like your vehicle’s chimney. Air pressure draws waste gases from the engine and then expels them into the atmosphere.
Sometime these gasses are expelled as smoke, and with modern cars becoming increasingly fuel efficient with less emissions it is becoming easier to spot problematic smoke coming from your engine.
An occasional puff of smoke from the exhaust should not cause you any worry. However if you are noticing persistent smoke coming from your car it could spell trouble. Check out what different coloured smoke could mean for your engine with our helpful article.

The EGR (exhaust gas regulation) valve helps reduce emissions from your car. It effectively channels some of the exhaust gasses back into the combustion chambers of the engine, helping cooling.

The exhaust downpipe is the piece of the exhaust that connects the catalytic converter to the final exhaust tip or flange. This is a very small piece of pipe that can often become damaged from rust, wear and fatigue.
