Catalytic Converter options in California? for 2001 X5 3.0i??
 

So my car has Over 160,000 miles :thumbup: and my cats are plugged :thumbdown. Dealer price quotes are around $1600 for 2 of them.

Are there any aftermarket catalytic converters for the 3.0i? Apparently the cats on this care are part of a larger manifold which makes things a little more complicated than usual. Supersprint makes them, but are more expensive than OEM.

Any input?
