Most Huyndai cars that don't come directly from the factory have a vortex exhaust system and use a pipe that is smaller in diameter than the actual car needs to be added to the limit. In addition, the car must pass emission tests and be environmentally friendly.
Therefore, catalytic converters and exhaust systems must be installed at the factory. Installing a decent Hyundai i30 exhaust system can do anything from 3KW to 11KW in most cars.
Let's take a look at the different parts of the exhaust systems
Branch / exhaust manifold / collector
They take gas from various cylinders and usually collect it in a pipe that connects to another main pipe under the car. They are also flow tested to ensure that the air exits in the best possible way.

This pipe is in charge of connecting the branch with the catalytic converter and silencer. Usually, there is a straight road without many bends. The less bending, the better.
The job of the silencer is to drown out loud sounds. This is done by pumping sound waves into each other and thereby extinguishing them. Many cars have a second damper or even 2 parallel dampers.
The last part of the exhaust system. It consists of an exhaust pipe to the end. Many aftermarket exhaust pipes have beautiful chrome exhausts, single or dual. There's a lot of twisting here as the tube has to bend up and over the rear axle. Some providers even have exhaust lights.
