Complete exhaust system for Seat Leon Cupra 3 hatchback with sport catalyst

The kit includes:

• Downpipe with EURO 3 or EURO 4 catalyst 100 or 200 cpsi, • Round silencer, • Middle silencer with exhaust valve that allows you to choose between loud and quiet modes, • End pipes, • 2 carbon fiber exhaust tips, • Control unit with two pilots and batteries, • All wiring for connection

A sports catalytic converter from AWG Polonez was used for the exhaust system.

What is EURO norm?

• 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.

With an exhaust valve, the system will be used for longer trips in a quiet version, and on the track, adding to the sound of the engine. Installation is easy and there is no need for additional mounts. The system is entirely made of acid-resistant steel (T304, X5CrNi18-10, 1.4301, AISI 304, 0H18N9). Each element of the product made by CNC technology. The product comes with a 24-month manufacturer's warranty.
