<center><img src="http://pictureposter.audiworld.com/18814/dscn2322.jpg"></center><p>Last night while driving at close to open throttle, the cat dislocated from the turbo. Has this ever happened to anyone else? Should I have it welded or should I replace the cat? If I should replace the cat, should I go aftermarket and what are my options? Should I pop in a newer turbo while I'm down there (car has 90K). And finally, is it safe to drive to the shop?

Thanks,
Jon G

i thought someone posted that its illegal to repair a cat. though some places will do it.

also audi's warranty is much higher for the exhaust equipment...hopefully someone can confirm this.

You can have it rewelded. People have stated that the cat to cat flange is simply a press fitting (cheap), so it will come out over time. Welding it should be a permanent fix.

You're fine to drive on it, though you'll run pretty rich. As others have said, have it welded. If you can't find anyone to weld it, you can find a drop-in replacement at ECS Tuning. Good luck

Since you don't have emissions testing.

just replaced both of my cats in my 97 a4 2.8 Man it was a pain in the ***. I got 2 aftermarket ones. The dealer wanted $1000 for each cat and 250 for labor i was like no F**ken way. i went to www.all-catalytic-converters.com and bought my cats for 250 a piece what a deal!!. and when i installed them both and installed new sensors man now it sounds great. these guys do a good job. i suggest calling them they have a friendly associate. i talked to mike well anyways im out.
