NO MORE P0420 CODE!
I'm not here to persuade any one to use OE parts from the factory, but when your faced with a part that is $1000 from VW and less than $200 aftermarket, I think you'll make the right decision. The cat was exactly the right fit for my MK 4 Jetta with the 2.0L AZG type motor. Be sure to know what motor type you have as there are 3-4 different types in these Jettas and some have 4 or 6 bolt flange configurations. The best part is my P0420 code never returned and I passed my AZ emissions!
Trying to pass CT. State Emissions, which is one of the finest scams this country has ever come up with. After spending $300 for a "Tune Up" and still not passing, I found out from VW expert that the so called "Tune Up" I paid for was nothing more but new spark plugs (and the wrong plugs at that, for a VR6, not a 4 cyl.) Finally had to do a new enition coil, wires, plugs, the Catalytic Conv. still read fault and would not pass. The dealer and Napa, Autozone gave me prices of $350 to $675! Without labor. Found the Magnaflow on Ebay from AutoAnything for $110 incl. shipping!!! Couldn't beleive it. Got it, paid $120 to have it put in and PASSED yesterday. Also, the guys at AutoAnything were incredibley responsive to all my question and I will buy from them again.
