Default Help: Need catalyser replacement

Hallo, i am from austria and proudly owner of an 07-S281 SC #95.

At first, sorry for my english, that is not so good.

My engine light is on because one of the catalyser may be defected or rather works not correct.

Question: which Y-pipe and catalytic converter should i buy? The original one from Ford or can i also use some from magnaflow?

Enclosed i put a photo from the catalyser and emmsion control information.

An other question regarding motor oil. Is it better to use 5W20 or 5W30. The oil filler cap say 5W20 and the manual 5W30. Ist there a problem if i use 5W20?

I know, i am not the first saleen owner who ask this question, but i am not sure which one i should use.

Thanks for the help.

You may have a bad O2 sensor. If your OBD scanner is telling you the left catalytic converter is faulty then swap the O2 sensor between the left/right side then clear the codes and run the car to see if the check engine light comes on again. If it shows the right converter is bad then you just need to change your sensor.

Thanks for the very fast answer.
My mechanician has tap off the catalyst and one of them is loosely.
He clear the code and up to now the engine light is ok. But i think in few days the light comes again . That´s why i ask if i should use original Ford catalytic converter or another one. The original is very expensive if compared to magnaflow for example.

If you need new converters and can legally run the replacement MagnaFlow H-pipe in your country, then save money and order the MagnaFlow replacement.

The oil cap is a stock Ford item for the 4.6 Mustang GT. 5W20 is what Ford recommended for a stock GT. Saleen recommended 5W30 after their conversion.
