Allows you to delete the catalytic present, continuing to maintain the attack of the oxygen sensor and the thermocouple.

Catalyst to be applied on external wastegate.

Y-sleeve in stainless steel

This special resistor allows you to remove the error-fault resistor Lambda probe-

Spacer for the lambda probe which moves the oxygen sensor away after the catalytic converter which on some cars allows the "engine failure" warning light to come on when the exhaust system is deprived of catalytic converter, avoiding making any changes to the car's electrical system

Sost.kat to double the original parts.

This emulator prevents the "engine failure" warning light from turning on when the 3-way valve of the pierburg type or similar solenoid valves is removed from the system. Complete with connector, it attaches and works immediately
