New 200 cell CATS
#2
Be careful. I see you're in Los Angeles, like me. Beware of the Gestapo when it comes to Smog Check time. I had some 200 cell cats on my old XJ but got rid of the car before smog was due again, so I have no idea whether or not they would've passed. I kept the factory units in case I had to swap them back in.

What’s with all the negativity? What makes you think that I’m taking the cats off? Did you assume this? I’ve got the smog covered. I wouldn’t have changed them if I didn’t have a back up plan. It may not be a XKR but it’s mine. I’m customizing it to my liking no one else’s. I’m not trying to race or beat anyone.

P.s I can vouch for Stuart, great guy, doesnt have a condescending bone in his body. Not the type that thinks the rest of the world are fools (like some).

Thanks for leading the charge on this pilgrim. We will all need cats one day and you are showing us the way.

You could try O2 extenders...that got rid of the CEL on my old XJ. Not sure how it affects fueling though.
Do you have the 4.2 or 5.0? Have you noticed any change in throttle response or in the power band? When I installed sports cats on my old 4.2, I noticed a lot more power in the mid-upper range but I was never sure if the power band just got moved up a notch instead of actually adding power. I always had the sneaking suspicion that my throttle response and low-end torque had decreased a bit.

Yes, you're right - he is the pilgrim who is leading the charge to show us the way. LMAO! His problems so far tell me that those 200 cell cats are the wrong way! They'll work, eventually, given enough of his time and his money.
