It is a requirement for cars to be equipped with a catalytic converter, or “cat”, which is part of the car’s exhaust system. Removing the cat is therefore illegal.

Exhaust tips are an easy way to add some design flair to your car without splurging on a full system. Surprisingly, they can actually affect the sound.

Preparing catalysts by sending hot, steamy car exhaust over them could improve their efficiency and reduce the amount of rare and expensive metals required in vehicle catalytic converters and many ...

Explore the precision and expertise behind the manufacturing of car exhaust systems, where advanced engineering meets high-quality craftsmanship. From shaping durable stainless steel to applying ...

There are so many cars with weird, interesting, unique exhaust designs out there, and y'all had a lot of good suggestions, so I narrowed it down to 15.

IC engines have long received flack for how wasteful they are. That may soon change, as a team of researchers claims to have discovered the means of converting exhaust heat into energy, using a ...

Car exhaust fumes are toxic when inhaled, but a new study found that another car byproduct could be worse.

Tiny particles released when brakes wear down, can trigger inflammation and other health issues and could be worse than diesel exhaust in some cases.

Car brake dust can be more harmful than diesel exhaust There is a huge body of evidence showing that airborne dusts are damaging to our health.

Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these ...

Exposure to air pollution is associated with around 7 million premature deaths per year across the world. When we think of urban air pollution, diesel exhaust emissions are often portrayed as a ...

Studies indicate that, because they tend to be heavier, electric vehicles can generate more non-exhaust dust than petrol or diesel vehicles – the zero-emission label is clearly not accurate.
