I love the way 50 series sounds when I turn on my car not to loud nice rumble just enough. Also when I drive turns heads just enough for the other guy too notice.keeps them guessing.
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!
Very nice product. Not impressed with nut bolt combination to attached to vehicle. But, workmanship and finish are superb.
