Take it to a muffler shop and have them cut the old one out and weld a new generic one in. You might spend about $400 total. However 1500 to install a factory cat is not too bad. Some VW cats cost more than that without labor.

But I think I would spend the money for a second diagnosis at another dealer or shop first.
Sometimes a bad sensor can mimic a bad cat.

Agreed. A bad O2 sensor will sometimes look like a bad cat on a scanner. The bad thing is, unless the cat is rattling or there are other symptoms of a clogged or bad cat, they will have to test the O2 sensors which they will charge you for. However, it could end up being less expensive if it is only an O2 sensor. I would suggest taking it to a reputable shop that isn't a chain like midas. Usually they aren't known for having the best techs (No offense to those that might work at one). Find a shop that has been around for a while and has a good reputation. Another option is to see if any colleges in your area have a tech program and see if they will look into it. That may sound like a bad idea, but remember they have their instructor there to check their work plus labor is usually free or very cheap.

Good catch. I didn't realize it is set up that way. and after seeing the actual part, I dont think they would be able to weld one up. You can still take it to a muffler shop to see what they say. As for the warranty, if the car is still under warranty then yes it will be covered, however, the federal emissions warranty is only 8 years 80k miles, but if you purchased the car new it may still be under the 10 year 100k warranty. You can call the dealership and ask them about that. They will be able to tell you if the car is still waaranted if you give them the VIN number.

You can also buy an aftermarket replacement that fits just like the factory one. You'll need the exhaust manifold gasket, exhaust manifold, and exhaust pipe gasket. considering your location, it would be smart to get new bolts and nuts as well. The old ones may be rusted or siezed on. There are 9 nuts for the manifold and 2 nuts and bolts for the exhaust pipe.

if you want the cheapest solution look into getting a DEFOULER for the secondary o2 sensor
Yes, that would get rid of the check engine light, but it's not at all a solution as the O2 sensors help regulate fuel trim, you could potentially damage the engine if you didn't first fix whatever the problem is. and if it is a bad cat, you could end up really damaging the car in general if it's not taken care of. so yes, you could just stick an aftermarket header with no cat on there then install a non fowler and you would fix the cat issue and not have a check engine light, but you would still have the possible fuel trim issues.
