Default Catalytic Converter Suggestions to go with new exhaust

Here's the skinny...

I have a crack some where in one of my manifolds (can hear it during cold start). Took it in to local repair shop, they took a look, but couldn't pinpoint it before it would seal, long story short, it has to get worse before they can find and fix it... well that's a hell of a prognoses.

So, since I was most likely going to be replacing a manifold anyway, I thought it would be the perfect excuse to explain to the wife, "Well, I might as well get top of the line, so this doesn't happen again" = (in man speak) I ordered a pair of silver ceramic coated JBA shorties... and threw in a high flow Magnaflow Y pipe as well. Should all be in by tomorrow.

I already have a Borla XL muffler dumping pipes over my rear axle. So I was thinking, I'm going to be replacing the manifolds with shorty headers, putting on a new/better Y pipe, and replacing the piping in between... really only missing some new high flow cats. Any ideas on who/what/where? I see that Magnaflow makes a replacement cat for 2009 Dodge Rams (no pic), but I can't seem to find them anywhere. Don't even know if they are out yet. Guess I'll try calling tomorrow. You guys think these would work with the shorties? Any other suggestions, thoughts, etc.? Should I just use the stock ones? Although that would look kind of crappy, nice new shinny headers, piping, and Y pipe, with rusty old cats... anyway, let me know what you guys think.

- Thanks

That is why I asked for the year. 09 header bolt issue. Nothing wrong with the manifold.

It may matter to you if your header bolt is snapped off in the head
