I run twin Magnaflow 3" cats in mine. Magnaflow are a great quality brand but probably a bit more expensive than others out there. If you are looking at them for your I6, the stock one with just the openings brought out to 2 1/2" will handle up to 200rwkw which is plenty for most engines.
Ive this about the standards but looking at them they seem to join up to the headers on about a 25-30 degree angle. Is that bad?

Doesn't really matter what angle they are at, they do this to get the cats as close to the engine as possible which gives the least emissions. I assume you are running stock headers as most extractors run the cats well back under the car. Extractors would be the first step because they would be the biggest restriction.
