Change dramatically the sound of my truck, it feels more quick in acceleration. Not yet measure if there is any mpg increase.

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!
