The catalyst forces the passage of air and gases emitted by the engine through tiny ducts. By removing the catalyst, the engine breathes better and develops more power. The sound is also improved and fuel consumption can be reduced, up to 10%, depending on the car model. The catalyst suppressor is, broadly speaking, an element that is used to replace the catalyst and eliminate the effect that it can produce on the control of exhaust gases. Like many engine parts and accessories, the catalytic converter has a lifespan. The optimal period of operation of a catalytic converter is around 80,000 km, also depending a lot on the care and maintenance to which the car has been subjected during the mileage.
