Automobile engines are always connected with a pile of twisted and bizarre metal pipes. These pipes are divided into multiple pipes, made of cast iron or welded with stainless steel. Their scientific name is exhaust manifold.

The 400 horsepower exploded by the 2.5T inline five-cylinder engine is seriously inconsistent with its compact body. Coupled with the easy handling characteristics brought by the short wheelbase, this kind of power is surging, and the feeling of where to hit is fascinating.

The three-way catalytic converter is a metal device installed in the exhaust system of a vehicle. Its purpose is to reduce the pollutants released into the atmosphere when the internal combustion engine is running. They are made of precious metals, including platinum, palladium and rhodium.Although it was first introduced to the U.S. market in the 1970s due to EPA requirements. However, other countries began to pass laws mandating installation. That's because three-way catalytic converters have done an excellent job of reducing pollution in cities like Los Angeles, which have a serious "smog" problem.

The muffler is an important structural element of the exhaust system, without which the operation of a modern car is simply impossible. A car muffler has the following main functions.

Many attentive riders will notice that many supercars, modified cars and racing cars will spit fire from their tails when shifting gears, cornering or even braking, and they will make a bursting sound, which is very shocking. Someone can't help but ask: What is the principle of the rear end of the car? Does breathing fire harm the car? Most importantly, will my family car spit fire?

Friends who are familiar with car modification know more or less about the knowledge of exhaust tail pipes. Although the exhaust pipe at the rear of the car looks like a small part, its image will affect the appearance of the entire car.

Why do so many people love "sports cars" enthusiastically, and want to come to "cool, chic and expensive" can briefly summarize the reasons. A sports car can show a person's identity, aesthetics and personality to a certain extent. When it comes to sports cars, the word "modification" is probably what many people have printed in their minds. A sports car is inherently inseparable from modification.
