What options exist for replacing the catalytic converters/exhaust manifolds? I have catalytic efficiency below threshold in both banks. BMW replacements are at least $800 per manifold which is more than the car is worth, a 2003 330xi with 260,000 miles. I called a junkyard recently looking for used manifolds and he told me he wasn't allow to sell used catalytic converters. Are there any other good options besides buying the BMW manifolds?

Catalytic converter replacement options?
used ones probably your best bet, ebay /CL / Marketplace
new aftermarket cats are still $400-600 each, and that's the non-cali versions
Just a quick search:

Not sure where you are located.
If in the US, does your state test for emissions on cars 15 yrs or older?
In my state, MA..They don't....so - in theory - you could flash the EU2 tune and turn off your post-cat O2 sensors, and SAP, the former will no longer record CAT efficiency. You will also lose your check engine light, although error codes are still recorded to be captured with a scanner.
The alternative is to:
1. buy OEM
2 remove your exhaust manifold and have a muffler shop weld in new, good quality cats
3. Buy cheaper Ebay or Amazon cats of unknown quality
4. Buy a parts car, keep the cats and sell the rest
5. find somebody parting a car with Cats

I cracked one of my cats, replacing my exhaust nuts and bolts. I got the same error codes, I used these.
The light is out, I wouldn't want to spent too much on my 200k 325i.

Some mounting nuts were more difficult to reach compared to OEM. I think your right the XI has slightly different bends. Go to the site.
