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.
Although I was unable to install it myself as I am mechanically inept for the most part, it was a relatively easy install from what I saw. If this is what you need, my opinion is do not hesitate to buy it. I stumbled on this website and it was the best thing to happen to me in regards to buying something I need.
