AWG Polonez catalyst 

What is EURO norme?

the standard of permissible exhaust emissions in new vehicles sold in the European Union and the European Economic Area. These standards were developed in a series of European Directives, which gradually increased their restrictiveness. Higher standard catalysts have better exhaust filtering properties and reduce more particles in the exhaust gas.

What is capacity (cpsi)?

The cpsi value literally means the number of cells per square inch - the more cells there are, the smaller they are, and therefore, the lower the cpsi value, the more permeable the catalyst itself. For the best possible flow, we recommend that you use a catalyst with the lowest cpsi value possible.

Thanks to the exhaust throttle, the system will be used on longer journeys in a quiet version, and on the track, emphasizing the sound of the engine.

Thanks to the use of a dedicated exhaust system, installation is easy and there is no need for additional fittings.

The system is entirely made of stainless steel (T304, X5CrNi18-10, 1.4301, AISI 304, 0H18N9). Each element of the product is made using CNC technology. The product has a 24-month manufacturer's warranty.
