I haven't even taken a look yet at the stock exhaust manifold/heat shields and crap surrounding them. How much of an annoyance is it going to be when I put this on? I can only imagine with the way new cars are, I'm thinking it would be best to go from underneath but anyone with input?
I'll check it out more closely on my own some other time, just curious.

The feed one looks like the O2 bung is where the pipes connect, right before the flange, but it's hard to tell.

I see that the RE-A header has the divider barrier in the middle pipe, but the OBX one does not have this divider tab......Does the Stock OEM exhaust manifold have this divider? Any performance difference. I suspect that some hot exhaust could escape from one rotor to the next without it.

That divider only goes in about an inch or so and doesn't really do anything. Why it is there is a good question. There is a divider inside the center exhaust runner inside the block that keeps hot gasses from blasting the side of the opposite rotor.

Bummed, but bring on OU!
From the pics, the quality looks pretty good. I'd probably smooth out those welds at the 3 pipe junction a bit, but otherwise, not too shabby for $300 and change. And at 14.4lbs, I'd bet that's a significant weight savings over the cast stock manifold. What diameter piping is that?

And it is 2.75" outlet.
And yah smoothing out the welds would be simple, its only that one spot that looks very messy.
