Need help identifying a pair of BBK cats

Just lucked into some BBK cats. Marked BBK, CA/CE 91800, 02/02. 2.5" ID, heat shields are 9" long. Lady I got them from had no info, just wanted them gone. I checked BBK's website and did Google searches, no luck. I left a message for BBK's tech line, but maybe somebody here has some info. My guess is they were cut off a 2002-era catted H or X pipe by the owner's ex. Anybody here have any clues?

 

Cut. They look like what comes on some of the BBK catted X pipes, but the info on the pipes doesn't say much about the cats themselves.

 

Right now I have stock 2.25"exhaust except for Flowmasters the PO had put on using badly welded adapters. I picked up a brand new 2.5" off road X pipe and some nice BBK shorties for cheap a while back, and recently got a used Flowmaster cat back, also cheap. I got these cats for free. My plan is to cut the X pipe and weld the cats in myself. That'll give me a complete replacement of my exhaust from manifolds to tailpipe. Total investment will be $250 max.

 

OK, took pics.

 

Thanks! Good to know. Not bad for free, eh?

 

Right now my sound is good with the only things not stock, including the cats, are the mufflers. The cat back I got from a guy who said it was too loud for his daily driver. Once I have the headers, 2.5" pipes, BBK cats, and Flowmaster cat back, it ought to sound even better.

 

BBK shorties.

 

BBK got back to me. These were on their H pipes back in the early 2000s, so my guess about them being cut off one was right. I figure bad idea to weld them directly in to the pipes in case they are bad and I have to get new ones anyway, so I'll weld on 2.5" ID connectors for now.

 

Already thought of that! Win-win either way. I just looked inside - very clean, and I can a little daylight. I was looking for an excuse to buy a welding table, and now I have one.
