Replacing exhaust manifold

[telemike]

I'm going to hopefully replace my leaky manifold soon. It's a 2007 3.7

My top pick is the Walker 16481 which I can find for $415 or less.

Magnaflow makes one but it is $704-714
Dorman has a cast iron replacement for $300
I'd love an OTT header, but I have to pass yearly emissions inspections (OBD II and visual), though I doubt most places actually look for the cats but do I want to chance getting caught?

Any thoughts on the Walker?

I just noticed that even though this is specified for my year, there appears to be only one o2 port.

I can get a magnaflow for a 2006 much cheaper than the 2007 model. It appears the main difference is a longer cat section. Will that matter? Both have two o2 ports. I saw aslaskadans pics and his 2006 manifold had two ports.
