"Let me just say that California is run by jacka**es! They seem to feel a need to change the laws here every six months! Buying a Cat in this state now got really expensive going to a muffler shop thanks to a law change as of 1-1-09. Is there an option? Yes and I got it here! With that aside my car passes smog with this cat! Enough said! I did it myself and saved BUKU dinero! The price was way reasonable! If you are a true do it yourself and need your car to pass smog... What are you waiting for! Magnaflow are excellent cats. It is slip fit on this particular one so that 2" pipe slips in with just the right amount of friction to insure a good weld (as long as you know what you are doing!) I was up and running to the smog shop in half a day! Need I say more???" posted by: Dr. Motorfinger on March 5, 2009
