If you’re tired of the noisy and messy exhaust noise of your car, then this is the solution for you.

Invidia r400 consists of three parts – the first part is a metal duct that extends from the engine bay to the rear of the vehicle, where it’s attached to the exhaust pipe.
The second part is a rubber insert that sits in the metal duct, and this reduces the noise produced by the exhaust. The third part is the muffler itself, which is made of ceramic material and is fitted inside the metal duct.
Can you install it yourself? Yes, It’s very easy to install and doesn’t require any special tools. All you need is a hammer and a screwdriver to put it together.
Once you have the system installed, you won’t hear any noise at all, as the muffler absorbs the sound produced by the exhaust.

How to Choose a Catback System for Your Car?
A Catback system is an essential component of the exhaust system of a vehicle. It’s required to connect the exhaust of the vehicle to the muffler. It is also used to direct the exhaust gases away from the vehicle.
A Catback system consists of four basic components,
- Muffler
- Exhaust pipe
- Pipe that directs the exhaust gasses away from the vehicle
- Connection of the pipe with the muffler
So, it’s important to know each part of a Catback system to make a conscious decision.
Mufflers
Basically, a muffler absorbs sound waves. They are generally designed to reduce the sound level of exhaust gasses.
Mufflers absorb high-frequency noises created by engines. As the sound waves are being absorbed by the muffler, the sound is being passed through.
The muffler is made of metal and is placed on the rear of the vehicle. It is a cone-shaped device, which is placed in front of the catalytic converter. The muffler is attached to the exhaust pipe.
Mufflers are connected to exhaust pipes via pipes. In between the exhaust pipe and the muffler is a metal pipe.
A catalytic converter is connected to a muffler by an exhaust pipe. Through the stainless steel pipe, exhaust gas passes.
Catalytic Converter
The catalytic converter is a cylinder-shaped device, which is placed in the engine compartment. The catalytic converter is usually placed on the back of the engine.
A vehicle’s exhaust system begins with this part. As a result of its metal construction, it converts toxic gases into non-toxic ones.
The catalytic converter is placed at the rear of the vehicle and is used to filter the exhaust gases and convert toxic gases into non-toxic gasses.
