Default CATS and exhaust?

Ok, so my current exhaust that was on the car when I purchased it last year was said to have new cats on it. but it doesn't look quite right. one side doesn't even bolt up correctly. Now with that being said I found a stock exhaust with an borla x pipe for a good price. After examining it, it looks like there are two small ***** or what appears to be cats just after the collector, then the larger cats just after that, then the o2 sensors. Am i seeing this correctly and are the pre cats really necessary i dont think my current exhaust has them hence why one side of my exhaust doesn't bolt up correctly. I did notice that one of the small ones was broken but the other one is fine should I replace the bad one? or bust out both of the pre cats to match. Are they really necessary? I would love to put full exhaust on it but cant afford that now plus i want to do all my performance upgrades at once. So for right now just some small things.

The pre cats aren't necessary but you may theow a code by removing them. If it were me I would probably leave it alone and save up for some long tubes. If you do that you could go catless or get some high flow cats, that's what I did. I have a set of shorty headers I would sell for cheap if you are on a budget and didn't want to go with long tubes.

What brand are they I might be interested. what would you want for them? How well was the fit?
