We have been selling and installing universal catalysts from one of the leading manufacturers in the world: Magnaflow Exhaust www.magnaflow.eu, and catalysts from Fennosteel OY www.fennosteel.com, since 1997. IMPORTANT! Before installing a catalyst, the owner of the car must diagnose the problem that caused the melting or deterioration of the existing catalyst. In addition, the owner must ensure that the fuel, ignition and exhaust systems of the car are working faultlessly. The catalysts have a two-year warranty against rusting through.
