MagnaFlow catalyst converters suck
MagnaFlow catalyst converters suck! Now keep in mind, this is for a California compliant CATs and fitted to a 2004 Subaru WRX. I mention that first because California has a ridiculously marked up price on all their CA. Compliant CATs. I paid $2500 for two CATs. The other issue is Subaru uses very high tolerance OEM CATs for their cars and the MagnaFlow unit just can’t compete with the OEM CAT. So your car is gonna throw check engine lights and have several codes. Nothing but drama. The warranty on the MagnaFlow units are only replacement, they will not refund your money. They have been nothing but headaches as a company to deal with. In California, it’s a monopoly. You have very few choices other than OEM. Buyer beware, I’d go elsewhere.
