Dont use after market cats they are more of a kitten than a cat and usually fail the mot emissions test also cars with 2 oxygen sensors in the exhaust see the poor performance of these non genuine cats and put the engine warning light on I have had loads of problems with non genuine cats. Also scrap metal dealers pay good money for faulty genuine cats but say non genuine cats are worthless just goes to show how bad they are. to replace it locate the cat undo the fixing bolts remove the oxygen sensor/s remote the cat and fit new 1
